OIF Approves IC-TROSA Implementation Agreement, Specifications Speed Delivery of a Higher Level of Integration for Transmit and Receive Optical Components

IC-TROSA IA enables miniaturization of optical transceiver modules and lowers the component cost for 400ZR, metro, data center interconnect (DCI) applications

Fremont, Calif.—September 23, 2019OIF, where the optical networking industry’s interoperability work gets done, continues its efforts to reduce cost and speed market adoption of next-generation solutions through the approval of the Integrated Coherent Transmitter-Receiver Optical Subassembly (IC-TROSA) Implementation Agreement (IA). IC-TROSA integration will be demonstrated during this week’s OIF Physical and Link Layer (PLL) Interoperability Demo at ECOC 2019 in Dublin, Ireland (OIF booth 441).

“The IC-TROSA project took an aggressive approach to coherent optical component integration and has delivered two new package designs incorporating TX and RX integration, common digital controls and performance monitoring all in a small form factor package,” explained Scott Grindstaff, Director R&D, ADVA, and IC-TROSA IA Technical Editor. “Additionally, package specific features such as fiber-free interface and solder reflow compatibility have been incorporated.”

The optical sub-assembly supports high-bandwidth and high-order dual-polarization quadrature amplitude modulation (QAM) operations and is suited for data center interconnect, metro and long-haul applications. As module sizes decrease, coherent optics components need similar size reductions to enable next generation multi-terabit switches, line cards and transport platforms.

“The IC-TROSA IA is a solution for density requirements for line cards, front-pluggable and future on-board coherent 400G+ optical modules,” said Karl Gass, OIF PLL Working Group, Optical Vice Chair. “It aims to standardize a photonic package for coherent applications that is easy to use while leaving the internal implementation to the vendor.”

The IC-TROSA Type-1 is optimized for silicon photonics technology and uses a surface-mount package with Ball Grid Array (BGA) electrical interface. Important advantages include an increased electrical bandwidth and solder reflow capability. The IC-TROSA Type-2 is optimized for Indium Phosphide technology and uses a gold-box package with flex-cable electrical interface. Important advantages include an integrated tunable laser and a duplex LC optical connector.

The IC-TROSA’s low power dissipation and miniature footprint enables small form factor digital coherent optics (DCO) transceivers in a QSFP-DD or OSFP form factor, as well as very high-density coherent line card or daughtercard designs. Devices can support multiple modulation formats, including QPSK, 8QAM, and 16QAM, at symbol rates up to 64Gbaud, enabling data transmission up to 600 Gb/s.

OIF Launches Two New Projects — Higher Baud Rate Coherent Driver Modulator and Low-Rate Service Multiplexing Using FlexE and 400ZR White Paper — at Q3 Meeting

Meeting also featured industry talk from Andrew Schmitt, Cignal AI, and initial discussions on next generation network operator requirements

Fremont, Calif.—August 14, 2019 – Member activity at this year’s OIF Q319 Technical and MA&E Committees Meeting in Montreal, Canada resulted in the launch of two new projects — a higher baud rate coherent driver modulator and a white paper detailing low-rate service multiplexing using FlexE and 400ZR.

Andrew Schmitt, founder and directing analyst, Cignal AI gave member attendees a brief overview of emerging pluggable coherent technologies and the opportunity this new market presents and had the opportunity to speak with members about current and upcoming OIF work.

“It’s clear that OIF is not resting after a successful effort to standardize 400ZR, proven by the launch of two new projects at the recent Q3 meeting,” said Schmitt. “Also, as interest in pluggable coherent solutions grows, it is good to see OIF soliciting feedback from additional network operators in order to shape requirements for next generation standards.”

NEW PROJECTS

The “Higher Baud Rate Coherent Driver Modulator” project will define a new version of the Coherent Driver Modulator supporting at least 96 Gbaud for the low modem implementation penalty segment of the coherent market for single optical carrier line rates beyond 400 Gbit/s. Designed for higher data rates and longer reach and optimized for performance, this project is the next generation of the High Bandwidth Coherent Driver Modulator (HB-CDM) Implementation Agreement (IA) published last year.

The second project start is for a white paper on low-rate service multiplexing using FlexE and 400ZR aimed at eliminating ambiguity and providing clarification on how 400ZR should be leveraged in multiplexing applications. Various network operators are looking for a multiplexing scheme to support lower-rate Ethernet clients (e.g. 4x100GE) into a 400ZR coherent line. This technical white paper will educate the market on how FlexE can be used to aggregate low-rate Ethernet services (e.g. 4x100GE) into 400ZR interfaces.

OIF Continues Commitment to Interoperability with Two New Implementation Agreements – Specifications for CFP2-DCO and HB-CDM now available

Fremont, Calif.—May 21, 2019 – OIF, the global industry forum accelerating market adoption of advanced interoperable optical networking solutions, has completed two new Implementation Agreements (IAs) — the CFP2-Digital Coherent Optics Module (CFP2-DCO) and High Bandwidth- Coherent Driver Modulator (HB-CDM).

“As a member-driven organization, OIF’s work is based on our members’ needs. The CFP2-DCO IA is in direct response to feedback from a network operator that needed an IA to fill an interoperability gap in their network,” said Karl Gass, OIF, PLL Working Group – Optical Vice Chair. “The HB-CDM IA addresses a performance need by creating a component that can be used for much higher performance links.”

CFP2-DCO

The CFP2-DCO IA defines the additional information needed in order to implement the DCO function in the CFP2 module. The CFP2-DCO module contains all the required functions to perform dual polarization coherent optical signaling. The module can also provide different bitrates such as 100G/200G/300G/400G and support more modulation formats.

HB-CDM

The IA for HB-CDM targets modulation and data-rate agnostic coherent applications having nominal symbol rates up to 64 Gbaud. It defines a small form factor electro-optic component that integrates the HB-Polarization Multiplexed-Quadrature (HB-PMQ) modulator plus the RF drive functions for the high baud-rate and low modem implementation penalty segment of the coherent market. Additionally, the IA identifies and specifies the common features and properties of coherent transmitters to enable them to broadly meet the needs of current and future coherent systems.

EE Web – 112G Digs in at DesignCon 2019

112G serial links have moved out of the lab and onto the exhibit floor. 56G ramps up while 28G goes mainstream.

By Martin Rowe, EE Web, 

Last year at DesignCon 2018, we witnessed high-speed digital designs that moved past 56 Gbits/s (56G) and onto 112 Gbits/s (112G). This year, DesignCon 2019 brought numerous demonstrations of 112G as the connectors and cables caught up with the silicon. While still appearing in technical papers and panels, 112G has certainly moved into the exhibit hall. Meanwhile, 56G has matured and is now a complete ecosystem.

When it comes to signal integrity and high-speed signals, transmission lengths certainly matter, especially with electrical signals over copper connections. Yes, optical transmission is an option, but nobody wants to pay for it. At a panel session on Jan. 31, OIF board president Nathan Tracy presented the table shown in Figure 1 that describes five OIF standards for different electrical transmission lengths.

Given a rule of thumb of 0.1 dB/in./GHz of insertion loss (Figure 2), PCB traces of, say, 10 inches are simply too long. That’s where cables that jump over PCBs have become popular.

Figure 2: Cable assemblies jump over PCBs to reduce insertion loss. (Source: Optical Internetworking Forum, Broadcom, and DesignCon)
Connectors for 112G took several forms at DesignCon, depending on the length of the transmission. For chip-to-chip or chip-to-module distances, sending 112G four-level pulse-amplitude modulation (PAM4) signals (28 GHz) over PCB traces results in excessive insertion loss. To get past that restriction, several connector companies have developed cable assemblies that jump over sections of boards.

The 400ZR demo consists of real-time Error Vector Magnitude measurements demonstrating the maturity of the methodology used for transmitter specifications. In addition, a hardware-based 400ZR installation will show how participants communicate a typical application case.

CEI-112G Demo

OIF is taking a lead role in moving the industry to the next generation with its development of electrical interface specifications for 112 Gbps per differential pair. Multiple live demonstrations featuring interoperability clearly prove the key role OIF provides. The CEI-112G demonstrations in the OIF booth will feature multi-party silicon supplier interoperability over mated compliance board channels and direct attach copper cable channels, all demonstrating the technical viability of 112 Gbps operation, along with multiple industry form factors including OSFP and QSFP-DD.

FlexE Demo

OIF continues to lead in FlexE aggregation architectures through its newest FlexE 2.1 project for FlexE over 50GbE PHY applications, an extension to its FlexE 2.0 Implementation Agreement (IA). The FlexE 2.0 demo will show off the bonding, subrating, and channelization features that allows FlexE-enabled hardware to support non-standard Ethernet rates over standard Ethernet optics. Realistic multi-vendor deployment scenarios, client rate reconfiguration, and in-band messaging features will be demonstrated on a network built from a variety of Ethernet optics and interconnecting the OIF and Ethernet Alliance booths.

OIF Experts to Provide CEI-112G Project Update at DesignCon

Expert panel will provide an update on the multiple interfaces being defined by OIF including CEI-112G MCM, XSR, VSR, MR and LR for 112G

Fremont, Calif.—January 23, 2019 – A panel of OIF experts will present and discuss the ongoing, multi-faceted Common Electrical I/O (CEI)-112G interface effort at this year’s DesignCon being held in Santa Clara, CA January 29-31. “112-Gbps Electrical Interface: An OIF Update on CEI-112G,” is scheduled for Thursday, January 31 at 3:45 pm (local) and will provide an update on the multiple interfaces being defined by OIF including CEI-112G MCM, XSR, VSR, MR and LR. Applications of these 112 Gb/s interfaces include die-to-die, chip-to-module, chip-to-chip and long reach over backplane and cables.

Panel speakers include Brian Holden of Kandou Bus and OIF member; Cathy Liu of Broadcom Inc. and OIF Board Member; Steve Sekel of Keysight Technologies and OIF PLL Interoperability Working Group Chair and Nathan Tracy of TE Connectivity and OIF President.

Since 2000, OIF has defined Interoperability Agreements (IA)s for electrical interconnects known as CEI.  CEI is a clause-based document that defines implementation details for interoperable electrical channels initially issued for 6 Gbps, then 11, 28, and 56 and includes definitions for multiple channel implementation topologies and will soon include 112 Gbps clauses. In August of 2016, OIF announced the first CEI-112G project in an overall effort that has now expanded to five projects.

“Previous CEI development has been highly influential and has been adopted, influenced or adapted by many other high-speed interconnect specifications throughout the industry,” said Tracy. “Given that the CEI-112G generation of high-speed transmitters, receivers and channels will be challenging to define, implement and measure, this panel will provide guidance to where the industry is headed and what the key challenge points are likely to be.”

The CEI-112G IA effort is challenging in signal integrity, implementation complexity and measurement terms. The signals are increasingly vulnerable to channel discontinuities, leading to signal impairment and crosstalk. The switching speed and the density of the available SerDes transistors have not kept pace with other silicon functions, resulting in architectural challenges. Finally, the ability to probe and repeatably capture measurements at these rates with sufficient accuracy and precision is challenging.

OIF Launches Flexe 2.1 Project and Elects new Board Positions and Working Group Representatives

This work continues OIF’s lead in FlexE aggregation architectures by keeping current with industry PHY rates

Fremont, Calif.—December 4, 2018 – OIF, the global industry forum accelerating market adoption of advanced interoperable optical networking solutions, today announced the launch of the FlexE 2.1 project and newly elected board members and working group chairs. The new project initiation and elections took place at the Q418 Technical and MA&E Committee meetings held October 29-November 2, 2018 in Sydney, Australia.

The new FlexE 2.1 project is for FlexE over 50Gbe PHY applications and an extension to the recently released FlexE 2.0 Interoperability Agreement (IA). FlexE 2.1 will specify a 50G FlexE frame and multiplexing format and will address Flex Ethernet (FlexE) applications with lower bandwidth needs and provide an implementation foundation for applications including the access layer of the future 5G mobile network. This new 50GbE support will extend the existing support for 100, 200 and 400GE in the just published FlexE 2.0 IA.

With market demand and possible large volume applications for channelization (5Gb/s granularity for minimum 10G clients) and bonding of 50GE PHYs in the future access layer/metro edge (based on IPRAN/PTN) of the 5G mobile backhaul network, FlexE implementation logic will be critical.

“There is continued demand by data center and network operators for a solution for flexible deployment and provisioning of Ethernet bandwidth,” said Dave Ofelt, Juniper Networks and OIF Physical and Link Layer (PLL) Working Group – Protocol Vice Chair. “Building on OIF’s great work for FlexE and FlexE 2.0, this new FlexE 2.1 project will ultimately result in a single IA that adds n×50Gb/s support to FlexE 2.0, along with other possible feature enhancements.”
