OIF Reveals OFC 2018 Interoperability Demo Plans

Forum Industry Experts to Conduct Panel Discussions

The Optical Internetworking Forum (OIF) today released the public multi-vendor interoperability demonstrations that it will conduct at Booth #5525 at OFC in San Diego, March 13-15, 2018. The demos will showcase three significant technologies; Flex Ethernet (FlexE), 112 Gbps per lane live electrical signaling and end-to-end optical links using CEI-56G-VSR electrical interfaces. In addition to the live demonstrations, OIF industry experts will conduct two panel discussions at OFC.

There are 14 participating companies including Amphenol, Credo Semiconductor, Fiberhome Telecommunications Technologies Co., Ltd., Finisar, Huawei Technologies Co., Inphi, Keysight Technologies, Molex, TE Connectivity, Tektronix, VIAVI Solutions, Xilinx, Yamaichi Electronics, and ZTE Corporation.

“The OIF continues to test and validate the implementation agreements the forum is working on or has recently completed,” said Steve Sekel of Keysight Technologies, Inc. and the OIF’s Physical and Link Layer Interoperability Working Group Chair. “The OIF recently published both CEI revision 4.0 which includes CEI-56 Gbps requirements and the FlexE revision 1.0 specification.  The forum also started work on four CEI-112 Gbps projects so this demo provides important insight into the potential technical solutions.”

Flex Ethernet Demo:

The FlexE technology from the OIF extends standard Ethernet with bonding, subrating, and channelization features and is defined in the FlexE v1.0 Implementation Agreement.  The demo features interoperability among member companies using combinations of these three features over multiple types of 100 GbE.

56 Gbps Demo: 

This demo features multiple silicon suppliers operating over a 56 Gbps PAM4 VSR (chip to module) link reflecting the recently published CEI 4.0 document that includes this 56 Gbps PAM4 channel definition.  The 56 Gbps demo will electrically drive interoperating optical modules, interconnected with fiber, showing a full multi-vendor electrical-optical-electrical link from host-to-host. The broad range of technologies and suppliers participating in the demo indicates the maturing industry ecosystem around 56 Gbps signaling.

112 Gbps Demo:

The OIF recently began new projects to define 112 Gbps per lane interoperable serial electrical channel definitions. As part of that effort, the OIF will be presenting two 112 Gbps serial electrical demos at OFC 2018.  The first demo will include a silicon chip driving a VSR (chip to module) channel and the second will have a silicon chip driving a direct attach copper cable assembly. 112 Gbps electrical signaling is regarded as a necessary technology to enable future signaling bandwidth requirements.

OIF Delivers on Another Industry First!

OIF member companies have teamed up to demonstrate significant progress in delivering an interoperable ecosystem of suppliers and solutions for critical market needs:

  • FlexE (Flex Ethernet)
  • 112 Gbps / lane live electrical signaling
  • End to End (host to host) optical link using electrical 56 Gbps – VSR, included in newly released CEI 4.0

Public demonstrations will be on display March 13-15, 2018 at OFC in San Diego, CA in OIF Booth # 5525 . Additional information can be found at

OIF CEI Technology for 56 Gbps Available for Wider Industry Adoption

The OIF announced today the publication of the “Common Electrical (I/O) CEI 4.0” with a focus on Serdes standards for 56 Gbps. This is the first completion of Serdes standards for the CEI generation of 56 Gbps I/O devices and adds PAM-4 and Ensemble NRZ as additional advanced modulation schemes to NRZ. Preliminary testing of 56 Gbps work has also been demonstrated by OIF members for the past two years at OFC where chip designers, connector vendors and test equipment suppliers showed the viability of the electrical channel parameters.  CEI 4.0 represents the eighth generation of OIF electrical interfaces over an 18-year span.

“The industry continues to face challenges for diverging requirements regarding link latency and concerns with power consumption at the higher data rates,” said Klaus-Holger Otto of Nokia and the OIF Technical Committee Chair.  “Documenting channel definitions in more granular reaches and multiple modulation schemes allows for the optimization of silicon chip designs, channel architectures and network operator use cases. These parameters for 56 Gbps will be used as building blocks for protocol specifications written by other organizations across the industry so the forum wanted to provide definitions that met their unique needs.”

The result is a number of carefully optimized channel definitions that will enable the industry to benefit from a range of interoperable solutions at 56 Gbps data rates. Key to this effort was aiming for the lowest possible power dissipation for each application while balancing link budget and latency. At this time the OIF is releasing CEI 4.0 with the following new clauses:

  • CEI-56G-USR-NRZ: Ultra Short Reach, die-to-die inside multi-chip-modules, NRZ modulation
  • CEI-56G-XSR-NRZ: Extra Short Reach, chip-to-driver, NRZ modulation
  • CEI-56G-VSR-PAM4: Very Short Reach, chip-to-module, PAM-4 modulation
  • CEI-56G-MR-PAM4: Medium Reach, chip-to-chip, one connector, PAM-4 modulation
  • CEI-56G-LR-PAM4: Long Reach, chip-to-chip, two connectors over backplane, PAM-4 modulation
  • CEI-56G-LR-ENRZ: Long Reach, chip-to-chip, two connectors over backplane, ENRZ modulation

The CEI 4.0 can be found here. Further clauses with additional modulation variants of the above reaches will be added in a future CEI 4.1 release.

OIF Launches CEI-112G Projects, Forms Network Operator Working Group

The Optical Internetworking Forum (OIF) announced that it has begun work on long reach (LR) and medium reach (MR) CEI-112G, building upon two existing 100G serial electrical link projects. Forum members continue to support and approve the development of projects addressing CEI-112G as bandwidth needs increase. Dr. Chongjin Xie of Alibaba was invited to present to members at the quarterly meeting in Shanghai. Dr. Xie shared with members the need for various network technologies, innovations and breakthroughs for datacenters. Following the meeting, the members participated in an OIF Day with China Unicom and SK Telecom.

CEI-112G Projects

The CEI-112G-LR project defines an interface to enable high-loss 112G backplane channels. This project will also facilitate direct attach copper (DAC) cable channel links at 112G. The CEI-112G-MR project will develop specifications for a chip-to-chip (c2c) interface which can also be used to support applications of 112Gx2 (224G), and 112Gx4 (448G) with reduced power, complexity, and enhanced density.

“These projects build upon the relevant and foundational 56G and 112G CEI roadmap the OIF has established,” said Nathan Tracy of TE Connectivity and OIF vice president of marketing.  “The industry continues to look to the OIF to deliver interoperable implementation agreements that will drive adoption of both 100 Gb/s serial applications and the interfaces needed to address higher bandwidth.”

Network Operator Working Group

Members voted to evolve the Carrier Working Group into the new Network Operator Working Group, reflecting the active participation of web-scale and content service provider members such as Alibaba, Google and Microsoft, along with traditional service providers such as China Telecom, Orange, TELUS, and Verizon.

“The new working group reflects the OIF’s growing membership of network operators who are participating in technology advancement and interoperability demonstrations to influence the industry,” said Dr. Junjie Li of China Telecom, the newly elected Network Operator Working Group chair.  “These network operators have driven the OIF 400ZR and CFP2-DCO projects and are sharing their insights as reflected in the presentation from our Q4 speaker, Dr. Xie of Alibaba.”

OIF Announces Board Elections and New Project Starts

The Optical Internetworking Forum held their fourth quarter meeting this month in Auckland, New Zealand, resulting in several new project starts and board elections.  The OIF also held an interactive educational workshop with Spark New Zealand, a New Zealand-wide communications service provider.

“The OIF continues to work with other standards bodies and the industry to identify a wide range of technology needs that cross the entire optical and electrical ecosystem,” said Karl Gass of Qorvo and the OIF’s Physical Link Layer working group optical vice-chair.  “The OIF remains committed to providing technology direction that provides a path to interoperability in a pre-competitive environment. The projects started during the Q4 meeting demonstrate the OIF’s commitment to work with other standards bodies in the industry.”

 400ZR Interoperability

This new project will develop an implementation agreement for 400G ZR and short-reach DWDM multi-vendor interoperability.  It is relevant for router-to-router interconnect use cases and is targeted at (passive) single channel and amplified DWDM applications with distances up to 120 km. This project should ensure a cost-effective and long-term relevant implementation using single-carrier 400G, coherent detection and advanced DSP/FEC algorithms.

Common ACO Electrical I/O

The project will define the ACO electrical I/O independent of the choice of form factor and optical carrier count for 45 Gbaud and 64 Gbaud per-carrier applications. This project would build upon the success of the CFP2-ACO but is form factor agnostic so that it could be applied to multiple applications such as  CFP4, CFP8, QSFP, micro QSFP and OFSP.

Coherent Modem Management Interface

Members have requested that the industry combine the coherent modem management interface specifications [4″x5″ LH MSA, CFP2-ACO, CFP2-DCO, Flex-Coherent, etc.] into a standalone document.  OIF leadership, working in conjunction with the CFP MSA group, is inviting companies to participate in creating a complementary Normative document.

High Baud Rate Coherent Modulation Function

This project will define a small form factor component implementation agreement that combines the high baud-rate PMQ (HB-PMQ) modulator plus the RF drive functions into a single component. This new component will be used in conjunction with a high baud Integrated Coherent Receiver (ICR), a micro Integrable Tunable Laser Assembly (ITLA) and a coherent DSP, to implement a high performance coherent modem.

OIF Day with Spark New Zealand

The OIF continues to leverage the unique OIF Day program platform to reach out to key industry players for technical and strategic input. In conjunction with the Forum’s recent quarterly meeting in Auckland, the OIF hosted a half-day interactive and educational workshop featuring OIF and Spark New Zealand subject matter experts. The event achieved the objectives of introducing OIF work projects to this local service provider and obtaining valuable input on regional business and technical network challenges.

OIF Election Results

Dave Brown of Nokia was re-elected to the Board for a two-year term and appointed as president.  Re-elected to one-year terms were Junjie Li of China Telecom and Dave Stauffer of Kandou Bus. Stauffer will continue to serve as secretary/treasurer. Jonathan Sadler of Coriant and Nathan Tracy of TE Connectivity were elected to the board for two-year terms.  Tracy was appointed as vice president of marketing.

OIF Updates Micro Intradyne Coherent Receiver IA for Beyond 100G Applications

Forum soliciting input for next global interop demo

Optical Internetworking Forum (OIF) members recently approved important updates to the Micro Intradyne Coherent Receiver implementation agreement. The IA introduces three classes of receivers, distinguished by their RF frequency response, to support Flex Coherent DWDM transmission to 400G and beyond.

The OIF continues its efforts to look beyond 100G by selecting a 400G implementation technology option. The newly published Flex Coherent DWDM Transmission framework document specifies a single technical approach for diverse network applications, including long-haul (LH), metro and data center inter-connection (DCI).  One of the objectives of this work is to provide direction on the technical developments required by system and component providers.

“Our system vendor members continue to flow down future system requirements so that component suppliers can be ready with products to support their designs,” said Karl Gass of Qorvo and the OIF’s Physical and Link Layer Working Group – Optical Vice Chair.

The OIF’s 400ZR coherent interface starts to take shape

Roy Rubenstein, Gazzetabyte

June 23, 2017

The Optical Internetworking Forum’s (OIF) group tasked with developing two styles of 400-gigabit coherent interface is now concentrating its efforts on one of the two.

When first announced last November, the 400ZR project planned to define a dense wavelength-division multiplexing (DWDM) 400-gigabit interface and a single wavelength one. Now the work is concentrating on the DWDM interface, with the single-channel interface deemed secondary.

“It [the single channel] appears to be a very small percentage of what the fielded units would be,” says Karl Gass of Qorvo and the OIF Physical and Link Layer working group vice chair, optical, the group responsible for the 400ZR work.

The likelihood is that the resulting optical module will serve both applications. “Realistically, probably both [interfaces] will use a tunable laser because the goal is to have the same hardware,” says Gass.

The resulting module may also only have a reach of 80km, shorter than the original goal of up to 120km, due to the challenging optical link budget.

Origins and status

The 400ZR project began after Microsoft and other large-scale data centre players such as Google and Facebook approached the OIF to develop an interoperable 400-gigabit coherent interface they could then buy from multiple optical module makers.

The internet content providers’ interest in an 80km-plus link is to connect premises across the metro. “Eighty kilometres is the magic number from a latency standpoint so that multiple buildings can look like a single mega data centre,” says Nathan Tracy of TE Connectivity and the OIF’s vice president of marketing.

Since then, traditional service providers have shown an interest in 400ZR for their metro needs. The telcos’ requirements are different to the data centre players, causing the group to tweak the channel requirements. This is the current focus of the work, with the OIF collaborating with the ITU.

“The catch is how much can we strip everything down and still meet a large percentage of the use cases”

“The ITU does a lot of work on channels and they have a channel measurement methodology,” says Gass. “They are working with us as we try to do some division of labour.”

The group will choose a forward error correction (FEC) scheme once there is common agreement on the channel. “Imagine all those [coherent] DSP makers in the same room, each one recommending a different FEC,” says Gass. “We are all trying to figure out how to compare the FEC schemes on a level playing field.”

Meeting the link budget is challenging, says Gass, which is why the link might end up being 80km only. “The catch is how much can we strip everything down and still meet a large percentage of the use cases.”

400ZR form factors

Once the FEC is chosen, the power envelope will be fine-tuned and then the discussion will move to form factors. The OIF says it is still too early to discuss whether the project will select a particular form factor. Potential candidates include the OSFP MSA and the CFP8.

“The cloud is the biggest voice in the universe”

The industry assumption is that the 80km-plus 400ZR digital coherent optics module will consume around 15W, requiring a very low-power coherent DSP that will be made using 7nm CMOS.

“There is strong support across the industry for this project, evidenced by the fact that project calls are happening more frequently to make the progress happen,” says Tracy.

Why the urgency?

“The cloud is the biggest voice in the universe,” says Tracy. To support the move of data and applications to the cloud, the infrastructure has to evolve, leading to the data centre players linking smaller locations spread across the metro.

“At the same time, the next-gen speed that is going to be used in these data centres – and therefore outside the data centres – is 400 gigabit,” says Tracy.

 

OIF Approves Virtual Transport Network Service Implementation Agreement

Tad Hofmeister of Google joins board of directors

Members of the Optical Internetworking Forum (OIF) recently met in Ljubljana, Slovenia for a quarterly technical committee and approved an implementation agreement (IA) for an optical Virtual Transport Network Service.  They also made progress on the 400G-ZR project and were given a presentation on 100G and Beyond by Andre Pucko of Telekom Slovenije d.d.  Additionally, Tad Hofmeister of Google joins the board of directors, filling an open seat.

A Virtual Transport Network Service (VTNS) is the creation and offering of a Virtual Network (VN) by a provider to a user and is built on the virtualization of transport network resources. VNs may be dynamically created, deleted, or modified and users can perform connection management, connection monitoring and connection protection within their VN.

“Development of Transport SDN (Software Defined Networking) will enable service providers to offer new revenue generating services,”  said Lyndon Ong of Ciena and the OIF’s Market Awareness & Education Committee Co-Chair, Networking. “VTNS is one class of services of interest to many operators and can become a main driver for the deployment of SDN in their transport networks.”

In specifying the new VTNS IA, OIF identifies the requirements and characteristics of different virtual network service types, such as dynamic and static behaviors, as well as the attributes and parameters required for these service types and the requirements for support of service recovery and OAM. Different types of VTNS could be associated with operators offering, for example, Bandwidth on Demand (BoD) services, Network as a Service (NaaS) or Network Slicing for 5G Networking.

400G-ZR Project Update

The OIF’s 400G-ZR Interoperability project addresses both 400G ZR and short-reach DWDM multivendor interoperability such as might be required for cloud scale data center interconnect (DCI). The project made progress at the Q2 meeting by receiving 10 technical contributions addressing considerations such as power consumption of DSP, FEC proposals and experimental demos.  The work will continue to move forward with scheduled conference calls before the Q3 meeting.

OIF at Optinet China

OIF board member Junjie Li of China Telecom will speak at Optinet China in Beijing on June 13, 2017 at 12:25 pm.  Mr. Li will present “OIF Interop – the Key to Unlocking the Benefits of SDN”.

OIF Concludes SDN Transport API Interoperability Testing

The Optical Internetworking Forum (OIF) conducted a six-week long global testing of the Transport Application Programming Interface (T-API) standard from the Open Networking Foundation (ONF). The OIF managed the multi-location demonstration which started in mid-October 2016 and concluded in December 2016.  Vendor participants executed a multi-domain path selection and recovery test plan with intra-lab and inter-lab testing across five carrier labs located in Asia, Europe and North America. A technical white paper on the demonstration is available to download here.

“As operators move from SDN PoCs and lab trials into commercial deployments, lack of interoperability between the SDN controllers and the orchestration layer above has quickly become the biggest technical barrier for many operators,” said Sterling Perrin, principal analyst, Heavy Reading. “Building a standardized northbound interface and successfully testing interoperability across different vendors and different networks – as the OIF has demonstrated – is a major step forward in addressing the northbound interface challenge and bringing SDN architectures to wide-scale commercial use.”

OIF SDN Transport API Interoperability Demonstration

The Optical Internetworking Forum (OIF) and the Open Networking Foundation (ONF) are leading the industry toward the wide scale deployment of commercial SDN by testing key Transport Application Programming Interfaces (T-API). The interoperability test and demonstration, managed by the OIF, addresses multi-layer and multi-domain environments in the following carrier labs; China Telecom, China Unicom, SK Telecom, Telefonica and Verizon. These carriers defined real world use cases including multi-domain orchestration of services delivered through Ethernet, OTN and optical switching. Carriers and vendors demonstrated how Network Function Virtualization (NFV) and SDN configured connectivity are combined to deliver service life cycle management.

Participating vendors include ADVA Optical Networking, Ciena, Coriant, Huawei Technologies Co., Ltd., Infinera, Juniper Networks, NEC Corporation, Sedona Systems, and SM Optics. Consulting carriers include Orange and TELUS.  Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

Additional information can be found here.

Participants in the OIF Transport SDN interoperability event also submitted a proof of concept demo proposal to ETSI NFV.  The proposal, “Mapping ETSI-NFV onto Multi-Vendor, Multi-Domain Transport SDN”, was accepted and details are located here. The open demonstration of NFV concepts in a Proof of Concept (PoC) helps to build industrial awareness and confidence in NFV as a viable technology. Proofs of Concept also help to develop a diverse, open, NFV ecosystem. Results from PoCs may guide the work in the NFV ISG by providing feedback on interoperability and other technical challenges.

“Being able to dynamically establish connectivity between Virtual Network Functions enables carriers to provide greater service agility and reduce opex,” said Jonathan Sadler, of Coriant and the OIF Interoperability chair.  “Integrating multiple technologies using transport SDN further enables the right connectivity mechanisms used for service delivery.  Having this demonstration recognized by ETSI NFV provides building blocks for the development of future SDN-WAN.”

OIF Approves Agreement on Polarized Multiplexed Quadrature Modulator

Starts 112G inside Multi-Chip-Module Project, Google’s Bikash Koley speaks at Q1 Meeting

Members of the Optical Internetworking Forum (OIF) recently passed an Implementation Agreement (IA) for an optical integrated Polarization Multiplexed (PM) quadrature modulator for coherent applications with nominal symbol rates up to 64GBaud. The agreement supports the 16QAM modulation format for 400G applications.

“As we go to higher data rates, we need higher performing optical components that maintain a reasonable level of complexity.” said Karl Gass of Qorvo and the OIF’s PLL Working Group – Optical Vice Chair. “These components are targeted for 400G applications.  RF bandwidth is the highest priority for this project.”

The forum members also started the CEI-112G in MCM project to support interconnect within Multi-Chip-Modules (MCMs). In addition to the CEI-112G-VSR specification that is being developed, there is a need to support high rate interconnect amongst large logic devices as well as to small driver devices within an MCM.

Members have also started a maintenance project to produce amendments to the User Network Interface (UNI) 2.0 and External Network to Network Interface (E-NNI) 2.0 specification documenting the extensions for support of OTN rates higher than 100G. Adding these extensions to UNI 2.0 and E-NNI 2.0 will facilitate vendor interoperability.  The project seeks to assist the IETF as it develops the required routing and signaling extension by providing a description of the Byond100G data-plane and the operations to be controlled by GMPLS.

Also at the forums’ Q1 meeting, Bikash Koley, distinguished engineer and director of network architecture, engineering and planning at Google was invited as a guest speaker and presented on the Zero Touch Network.

Following the quarterly meeting in San Jose, a well-attended FlexE workshop was held. An overview of the completed and in process FlexE projects was provided, along with presentations and discussion on the future direction of FlexE. The workshop started with a summary of the FlexE 1.0 Implementation Agreement and was followed by an overview of the active FlexE 2.0 project.  Speakers and panelists include Luca Della Chiesa, Cisco; Tad Hofmeister, Google; Maarten Vissers, Huawei; Dave Ofelt, Juniper; Tom Issenhuth, Microsoft; Scott Irwin, MoSys and Stephen Trowbridge, Nokia.

OIF Announces 100G Serial Electrical Interconnect Workshop

The Optical Internetworking Forum announced today a half-day workshop, open to the public, featuring subject matter experts from the OIF and an industry view by Alan Weckel of Dell’Oro.  The workshop will address 112 Gbps per lane serial electrical interconnect needs and will take place concurrent with OFC on March 23, 2017 at the Los Angeles Convention Center.

In August 2016, the OIF began the CEI-112G project to define the serial electrical interface for next generation optical modules at 112 Gbps.  This technical work is expected to be the first of a series of CEI-112G clauses for various reaches, ranging from ultra-short reach interfaces designed for intra multi-chip module (MCM) communications to longer chip-to-chip interfaces.

“Operation of electrical interfaces at 112 Gbps speeds is feasible, but demands careful attention to some of the thorny technical issues that are involved and the technology trade off decisions that are going to be required,” said Nathan Tracy of TE Connectivity and the OIF vice president of marketing . “This workshop will present the multiple facets and perspectives for the 112 Gbps serial electrical development work including applications, equipment, optics, SERDES, connectors and channels.”

The first half of this workshop will focus on the industry view and application spaces for the next generation interconnects, including networking trends and cloud scale applications. It is anticipated that requirements for these application spaces are characterized by a combination of parameters such as:

  • loss budgets (distance, number of connectors),
  • electrical and optical data rates,
  • electrical channel properties,
  • power constraints,
  • equalization and retimers,
  • mechanical constraints (faceplate density, etc.)

The second half of this workshop will focus on potential electrical link and interconnect technologies being developed to support serial data rates of 100 Gbps and higher.

OIF Announces New Flex Ethernet Projects and Workshop

The Optical Internetworking Forum announced two new FlexE projects started at the quarterly meeting last month.  The OIF is also holding a workshop titled, FlexE Today and Tomorrow, in San Jose on January 20th.

“The datacenter and communications industries are demanding a solution for flexible deployment and provisioning of Ethernet bandwidth,” said Scott Irwin of MoSys and the OIF’s Physical and Link Layer (PLL) Working Group protocol vice chair. “Building on its first generation of FlexE, the OIF has started a new project to support the next generation of Ethernet PHY rates currently under development within the IEEE 802.3 Working Group.  Because of the large industry interest in FlexE, the OIF is also hosting a workshop on the topic which allows non-members to learn about the work first hand.”

The FlexE 1.0 implementation agreement, completed in March of this year, provides a mechanism to map one or more FlexE clients over a group of 100 Gb/s Ethernet PHYs.  The client rates supported are 10G, 40G, and n×25G.  The new FlexE 2.0 project will add the ability to create FlexE groups of 200 Gb/s and 400 Gb/s Ethernet PHYs and to consider several other feature additions.

  • More detail on use of FlexE management channels
  • Coarser calendar granularity to reduce gate count for high bandwidth devices
  • Management of skew for specific applications
  • Transport of frequency or time by the FlexE group

FlexE 1.0 and ongoing revision enable 802.1 LLDP over management channels for FlexE Connectivity Verification.  However, FlexE capabilities discovery is still required to facilitate the setup of FlexE Group(s) and Clients. The new FlexE Neighbor Discovery project will introduce some OIF organizational specific FlexE Extension to LLDP for FlexE capabilities discovery.

OIF Partners With UNH-IOL to Certify Optical Control Plane UNI

Enables Multi-vendor, Multi-layer Interoperability Using RSVP-TE Signaling

The Optical Internetworking Forum (OIF) today announced an agreement with the University of New Hampshire InterOperability Lab (UNH-IOL), an independent provider of testing and standards conformance services for the networking industry, to provide certification for Optical Control Plane User Network Interfaces (UNI) based on industry standards.  In line with OIF’s mission to enable global interoperability in optical transport networks, the Forum’s certification program will address the interoperability of optical and packet products, complementing OIF’s work on unlocking the benefits of SDN for carriers.

While an optical control plane is already deployed by a large number of operators around the world, interoperability between vendors is constrained by lack of an interoperable UNI. Multi-vendor interoperability of the optical control plane remains absent from commercial products, although various demonstrations have proven it is feasible.  The optical control plane facilitates operations and enables dynamic provisioning, restoration and optimization across optical networks. The UNI extends these capabilities to client nodes and the OIF’s UNI certification will help enable the availability of control plane interoperability in commercial products.

“The advent of interoperability in optical networks is a paradigm shift, which will dramatically increase flexibility and innovation in our networks,” said Philippe Lucas, SVP Strategy Architecture and Standards of Orange. “The OIF certification is a step to unlock the market by providing a unique reference and a critical market advantage to compliant, interoperable products.”

“The benefits of multi-vendor interoperability combined with certification can help broaden and accelerate the market for optical products, reduce costs, introduce new features and operational agility,” said Timothy Winters, Senior Executive of UNH-IOL.  “Certification can fulfill operator’s and vendor’s requirements with reduced repetitive testing and a higher level of confidence when going to market.”

“Development of the UNI certification test specification is happening at an important time in our industry,” said Tim Doiron, Principal Analyst Intelligent Networking, ACG Research.  “We’ve never gotten the optical domain out of vendor isolation when it comes to the optical control plane. Certification and interoperability will aid service providers in their migration toward a multi-vendor programmable, dynamic optical underlay with increasing automation, service agility and reduced operational costs.”

The Optical Control Plane UNI Certification Program

The new certification program, along with OIF’s well established and successful interop testing process and implementation agreements, helps the industry realize open, programmable and interoperable optical networks in commercial deployments, bringing to reality the promised benefits of transport SDN, with accelerated time-to-revenue coupled with increased operational efficiency. 

  • Certification is based on compliance with relevant industry standards including IETF RFCs on RSVP-TE signaling.
  • Addresses the main use cases enabled by an optical control plane, including simplified provisioning, automated path selection, dynamic restoration and multi-layer optimization.
  • Enables several deployment cases which are of primary importance to operators and require immediate interoperability, including IP/WDM integration, packet-optical interconnect, multilayer optimization and alien wavelength deployments.
  • Contributes to OIF efforts to unlock the benefits of SDN for flexible networks
  • Facilitates multi-vendor deployments.

Development of the UNI certification test specification is starting now. Visit the OIF webpage for more information. Formal testing of participating vendor products will start early 2017 and pre-testing is already open at UNH-IOL. The first OIF certified products are expected to be on the market in approximately 12 months from now.

To drive adoption of SDN, OIF demonstrates Transport Application Programming Interface (TAPI)

Ovum view

The goal of networking standards groups is to establish multivendor/multicarrier standards that interoperate. To achieve that goal, the OIF (Optical Internetworking Forum) is conducting a global interoperability demo to test software-defined networking (SDN) Transport Application Programming Interfaces (TAPI) among 5 global carriers and 11 system and software vendors. The tests cover services across optical, IP, and virtual appliance layers to see how services interact across the different vendors. In 1Q17, all issues identified will be presented to users and standard organizations to improve the performance and adoption of SDN. In doing this work, the OIF is performing a necessary step to drive adoption of multilayer and multivendor SDN.

OIF’s demonstration will lead to faster adoption of multilayer SDN

The OIF has been working to accelerate the deployment of new optical technology since its founding in 1998. In its 2014 demonstration of SDN transport architecture, the OIF established the need for common APIs for end-to-end orchestration for a multidomain network. Now, it is testing the Open Networking Foundation’s (ONF’s) SDN TAPI across 11 system participants: Adva, Ciena, Coriant, FiberHome, Huawei Technologies, Infinera, Juniper Networks, NEC Corporation, Sedona, SM Optics, and ZTE, with the support of five carriers – China Telecom, China Unicom, SK Telecom, Telefonica, and Verizon. The goal is to identify gaps in the current standards and work with standard bodies to address those gaps.

The demonstrations will abstract the topology for each carrier, including a virtual network in another carrier, setup of dynamic VNFs (virtual network functions), dynamic-connect IP services, and restore/setup of intra-lab optical connections. Each of these demonstrations will help vendors, carriers, and standard bodies see how complete the solutions are, and what needs to be done to progress multilayer interoperability between vendors and carriers.

Overall, the OIF is helping to move SDN and NFV (network functions virtualization) forward with the test of SDN TAPI. Vendors will benefit from knowing what applications need more work, and carriers will benefit from knowing how adoption of SDN/NFV can work across vendors and carriers so they can speed investment.

OIF Launches Optical Projects to Enable Next Generation Modules

At the conclusion of the Optical Internetworking Forum’s (OIF) latest quarterly meeting, the organization announced that it has begun work on two optical interface projects, marking an evolutionary step to integrate optics as the industry moves to aggressively shrink module size. The IC-TROSA project would enable manufacturers to have a higher level of integration for transmit and receive optical components. The OIF’s CFP2-Digital Coherent Optics (DCO) project will work with other standards bodies to implement coherent modulations formats in CFP modules.

 “The IC-TROSA project tackles much more than just a simple size reduction,” said Karl Gass of Qorvo and the OIF’s Physical and Link Layer (PLL) Working Group – Optical vice chair.  “It addresses optical packaging in a way that isn’t done in high volumes today. We want to come to industry consensus in this pre-competitive environment.”

Integrated Coherent Transmitter-Receiver Optical Subassembly (IC-TROSA) is the evolutionary step that combines Polarization Multiplexed Quadrature (PMQ) Transmitter (Tx) and Integrated Coherent Receiver (ICR) components to create a single integrated optics package.  The optical sub-assembly that supports high-bandwidth and high-order QAM operations is suited for data center interconnect, metro and long-haul applications. As module sizes decrease, current coherent optics components need similar size reductions to enable next generation multi-terabit switches, line cards, and transport. Density requirements for next-gen line cards, front-pluggable and future on-board 400G+ optical modules are driving the need for further integration and miniaturization.

The OIF’s CFP2-DCO project includes a way to build address management interface and identify registers necessary to talk to the DSP located in the module, specific to coherent modulation techniques. The CFP2-DCO is intended to be used for 100G, 200G or 400G applications for metro, long-haul and data center interconnections and it can support different formats such as DP-QPSK and DP-xQAM.

OIF Announces Plans for SDN Transport API Interoperability Demonstration

The Optical Internetworking Forum (OIF) announced today plans for a global Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) interoperability demonstration in the fall of 2016. The OIF is partnering with the Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open SDN, to take the testing into carrier labs worldwide and lead the industry towards the wide-scale deployment of commercial SDN. Network virtualization and flexibility to deal with peak traffic events, link failures and network slicing are driving motivations behind the demonstration. Currently the transport layer operates with no awareness of the packet layer above it, so manual intervention is often needed to address issues. By incorporating the T-API, the problems can be corrected automatically through software.

Host carriers for the demonstration include China Telecom, China Unicom, SK Telecom, Telefónica and Verizon. Participating vendors include ADVA Optical Networking, Ciena, Coriant, Fiberhome, Huawei Technologies Co., Ltd., Juniper Networks, NEC Corporation, Sedona Systems, SM Optics and ZTE. Consulting carriers include Orange and TELUS.  Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

“In the modern operating environment, carriers need to dynamically move capacity to handle quickly changing traffic demands,” said Jonathan Sadler of Coriant and the OIF’s technical committee vice chair and acting networking interoperability chair. “The APIs that are being tested create a new breed of applications. Like so many of the interoperability agreements developed by the OIF, demand from carriers continues to drive the technical direction of the Forum.”

“ONF and the OIF are united in our goal of moving these technical advances into the market for the benefit of network operators and their users,” said Dan Pitt, executive director of the Open Networking Foundation. “We are pleased to extend our longstanding collaboration with the OIF on T-API, leveraging OIF’s specialized optical expertise, and these demonstrations inspire operators and vendors alike to accelerate development and deployment.”

One main focus of the global demonstration is the notification interface – the means for notifying applications that congestion is being observed, triggering moving around of traffic and addition of capacity. Additional use cases based upon the API standards will be clarified during the testing and defined through OIF implementation agreements to provide a common set of requirements. Regional demonstration read-out events will take place in early 2017 and a whitepaper describing the event will be available to the public.

OIF Launches CEI-112G Project for 100G Serial Electrical Links

In the wake of its 3rd quarter meeting, the Optical Internetworking Forum (OIF) announced that it has begun work on a 100G Serial Electrical Link project. The very short reach (VSR) CEI-112G chip-to-module interface project is aimed at meeting the most immediate needs of the industry, with both shorter and longer reach projects expected to follow. CEI-112G-VSR will support a nominal lane rate of 112 Gb/s, enabling narrower interfaces to optical modules and is expected to be more energy efficient than previous interfaces. The CEI-112G-VSR specification doubles data rates over the current generation CEI-56G-VSR interfaces.

Following the OIF’s industry workshop “100G Serial Electrical Links and Beyond” in March, a large number of Forum members supported the development of an implementation agreement addressing CEI-112G. That workshop, held at OFC 2016, was open to the public and featured OIF and industry subject matter experts addressing both 100 Gb/s serial applications and the interfaces needed to address higher bandwidth.

“Optical lane speeds have run faster than electrical lane speeds since the introduction of 10G Ethernet. While this is not a problem in the early days of a new data rate, the lowest module cost is achieved when optical and electrical lane speeds are the same,” said Dale Murray, Principal Analyst with LightCounting Market Research. “The first optical modules running 100 Gb/s serial are expected in 2018, so now is the time for the OIF to begin work on this CEI-112G project.”

“As bandwidth increases, electrical interfaces need to reflect that trend. Given the lead times, development of standards for the next generation of electrical links needs to start now,” said David Stauffer of Kandou Bus and the OIF’s Physical and Link Layer Working Group Chair and board member.  “The OIF is continuing its roadmap for 100 Gb/s thru 400 Gb/s and beyond applications, addressing multiple reaches for chip-to-chip and chip-to module interfaces.”

OIF starts work on a terabit-plus CFP8-ACO module

The Optical Internetworking Forum (OIF) has started a new analogue coherent optics (ACO) specification based on the CFP8 pluggable module.

The CFP8 is the latest is a series of optical modules specified by the CFP Multi-Source Agreement and will support the emerging 400 Gigabit Ethernet standard.

An ACO module used for optical transport integrates the optics and driver electronics while the accompanying coherent DSP-ASIC residing on the line card.

Systems vendors can thus use their own DSP-ASIC, or a merchant one if they don’t have an in-house design, while choosing the coherent optics from various module makers. The optics and the DSP-ASIC communicate via a high-speed electrical connector on the line card.

ACO design

The OIF completed earlier this year the specification of the CFP2-ACO.

Current CFP2-ACO modules support single-wavelength transmission rates from 100 gigabit to 250 gigabit depending on the baud rate and modulation scheme used. The goal of the CFP8-ACO is to support up to four wavelengths, each capable of up to 400 gigabit-per-second transmissions.

This project is going to drive innovation

“This isn’t something there is a dire need for now but the projection is that this will be needed in two years’ time,” says Karl Gass of Qorvo and the OIF Physical and Link Layer Working Group optical vice chair.

OIF members considered several candidate optical modules for the next-generation ACO before choosing the CFP8. These included the existing CFP2 and the CFP4. There were some proponents for the QSFP but its limited size and power consumption is problematic when considering long-haul applications, says Gass.

One difference between the CFP2 and CFP8 modules is that the electrical connector of the CFP8 supports 16 differential pairs while the CFP2 connector supports 10 pairs.

“Both connectors have similar RF performance and therefore can handle similar baud rates,” says Ian Betty of Ciena and OIF board member and editor of the CFP2-ACO Implementation Agreement. To achieve 400 gigabit on a wavelength for the CFP8-ACO, the electrical connector will need to support 64 gigabaud.

Betty points out that for coherent signalling, four differential pairs per optical carrier are needed. “This is independent of the baud rate and the modulation format,” says Betty.

So while it is not part of the existing Implementation Agreement, the CFP2-ACO could support two optical carriers while the CFP8 will support up to four carriers.

“This is only the electrical connector interface capacity,” says Betty. “It does not imply it is possible to fit this amount of optics and electronics in the size and power budget.” The CFP8 supports a power envelope of 20W compared to 12W of the CFP2.

The CFP8 occupies approximately the same area as the CFP2 but is not as tall such that the module can be doubled-stacked on a line card for a total of 16 CFP8-ACOs on a line card.

Given that the CFP8 will support up to four carriers per module – each up to 400 gigabit – a future line card could support 25.6 terabits of capacity. This is comparable to the total transport capacity of current leading dense WDM optical transport systems.

Rafik Ward, vice president of marketing at Finisar, says such a belly-to-belly configuration of the modules provides future-proofing for next-generation lineside interfaces. “Having said that, it is not clear when, or how, we will be able to technically support a four-carrier coherent solution in a CFP8 form factor,” says Ward.

Oclaro stresses that such a high total capacity implies that sufficient coherent DSP silicon can fit on the line card. Otherwise, the smaller-height CFP8 module may not enable the fully expected card density if the DSP chips are too large or too power-hungry.

OIF goal

Besides resulting in a higher density module, a key OIF goal of the work is to garner as much industry support as possible to back the CFP8-ACO. “How to create the quantity of scale so that deployment becomes less expensive and therefore quicker to implement,” says Gass.

The OIF expects the work to be similar to the development of the CFP2-ACO Implementation Agreement. But one desired difference is to limit the classes associated with the module. The CFP2-ACO has three class categories based on whether the module has a limited and linear output. “The goal of the CFP8-ACO is to limit the designs to single classes per wavelength count,” says Gass.

Gass is looking forward to the CFP8-ACO specification work. Certain standards efforts largely involve making sure components fit into a box whereas the CFP8-ACO will be more engaging. “This project is going to drive innovation and that will drive some technical work,” says Gass.
