OIF Adopts Common Management Interface Specification (CMIS) Work Initiated by QSFP-DD Multi-Source Agreement

| | ,

Taking on the CMIS work reinforces and increases OIF’s significant value to the ecosystem   

Fremont, Calif.—January 5, 2022 – OIF is expanding its role in driving industry interoperability through the addition of the Common Management Interface Specification (CMIS) work initiated by the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA).  

CMIS may be used by pluggable or on-board modules, such as QSFP Double Density (QSFP-DD), OSFP, COBO, QSFP, and future module developments like co-packaged optics with host to module management communication based on a two-wire interface. This specification is targeted to systems manufacturers, system integrators and suppliers of CMIS compliant optical and copper modules. 

“The QSFP-DD MSA initiated the CMIS effort to address an industry need for commonality in managing pluggable modules, and it has been broadly and successfully adopted across the industry,” said Mark Nowell, Cisco, QSFP-DD MSA Group founding member and MSA co-chair. “OIF is very well suited to maintain and extend the development of this effort and I look forward to seeing their progress.” 

“Adopting CMIS from the QSFP-DD MSA, with the goal to build on and extend the specification is an ideal expansion of OIF’s work,” said Nathan Tracy, OIF VP of Marketing and TE Connectivity. “OIF is where the cloud gets its work done and extending CMIS is a giant step forward and an integral linkage to the other work that OIF members are doing to enable an interoperable ecosystem.” 

In August, OIF announced the new Physical & Link Layer (PLL) Working Group Management track to include the transition of ownership and maintenance of CMIS from the QSFP-DD MSA to OIF and a project to focus on CMIS extensions for co-packaging implementations. OIF will take over the ongoing CMIS revisions and further enhancements and CMIS extensions under this track. This track is co-vice-chaired by Gary Nicholl, Cisco and Ian Alderdice, Ciena. 

“OIF’s value to the industry is deep, as proven by the industry’s support and endorsement of this transfer of the CMIS work to OIF,” continued Tracy.  

The current CMIS and prior revisions (from QSFP-DD MSA) are now available to members on the OIF website.  “Archived Non-OIF Generated Specifications” can be found on the home page, on the “Documents” pull-down menu.

OIF Reveals New Common Electrical I/O Project to Strengthen an Open Ecosystem for Near Package Optics Architecture, Launches Management Track and Facebook joins Board of Directors at Q3 2021 Virtual Meeting

| | ,

Fremont, Calif.—August 27, 2021 – OIF’s Q3 2021 Technical and MA&E Committees Meeting, held virtually August 2-6, 2021, demonstrated OIF’s leadership in next-generation channel definition by revealing a new Common Electrical I/O (CEI) project. Two projects under the Physical and Link Layer (PLL) newly formed Management track were also initiated. Jimmy Yu, vice president of Dell’Oro Group, was featured as the guest speaker, and a new Board Member was appointed.

NEW PROJECTS:

The CEI-112G-Extra Short Reach (XSR)+ project will allow lower power, multi-source 112Gbps (optimized for 106.25Gbps) electrical I/O interface to be developed with advanced PCB and substrate technology. The project will also support an open ecosystem based on Near Package Optics (NPO) architecture. OIF members are proposing that an “XSR+” type interface is used to add reach for NPO applications over the existing XSR interface to enable a multi-vendor open ecosystem without adding significant power.

The two projects under the PLL Management track include one to transition ownership and maintenance of the Common Management Interface Specification (CMIS) from the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi-Source Agreement (MSA) to OIF, and the second project will focus on CMIS extensions for co-packaging implementations.

“Our quarterly meetings provide a critical platform for our members to discuss and debate interoperability challenges and industry standards that help OIF continue its mission to accelerate industry innovation,” explained David Stauffer, OIF Physical & Link Layer WG Chair and Kandou. “The new CEI-112G-XSR+ project will help strengthen an open ecosystem for NPO demonstrating OIF’s leadership in next-generation channel definition. Another significant new activity that addresses industry interoperability and standards is OIF’s new Management track. Due to the complementary/synergistic nature of the work with the OIF co-packaged optics, NPO, CEI and coherent optics projects, OIF will take over the ongoing CMIS revisions as well as further enhancements and CMIS extensions under this track.”

BOARD OF DIRECTORS APPOINTMENT

Rob Stone of Facebook was appointed to the OIF Board of Directors, filling an open position. Stone will serve the term for this position that goes through September 2022.

GUEST SPEAKER

Jimmy Yu served as the guest speaker providing OIF members with an update on the optical transport market. He leads Dell’Oro’s Optical Transport, Microwave Transmission and Mobile Backhaul Transport market research.

“OIF is a critical enabler to the optical market’s progression,” commented Yu. “The work of OIF members in these quarterly meetings to help guide interoperability is a significant benefit to the industry.”

FierceTelecom – What is 400ZR?

| | ,

Aimed predominantly at short-reach, single-span fiber optic links for Data Center Interconnect (DCI), 400ZR is an interoperable networking Implementation Agreement (IA) in progress by the OIF. It defines a footprint-optimized solution for transporting 400Gb Ethernet over DCI links targeting a minimum of 80 km. Enabled by advanced coherent optical technology design targeting small, pluggable form factor modules such as QSFP-DD and OSFP, 400ZR proposes a technology-driven solution for high capacity data transport, matched to 400GE switch port market introduction.
