OIF Releases Co-Packaging Framework Implementation Agreement

Framework serves as foundation for industry consensus on co-packaging with ASICs

Fremont, Calif. – OIF, the global industry forum accelerating market adoption of advanced interoperable optical networking solutions, today announced the release of a framework Implementation Agreement (IA) for co-packaging, identifying the critical co-packaged applications and their requirements and charting a path for interoperability standards.

OIF’s leadership in driving interoperability in co-packaging technologies began in 2020 when it was clear the industry needed to achieve consensus on standards. Since then, OIF members have engaged in an umbrella project to study the application spaces and relevant technology considerations for co-packaging of communication and computing interfaces with one or more ASICs.

The Co-Packaging track of OIF’s Physical & Link Layer (PLL) Working Group began by studying the application spaces contributed by the end-users. Then, it examined various related topics, including electrical and optical interfaces, thermal and mechanical considerations, reliability, safety, environmental and management interfaces. The findings of the work are summarized in the Framework Document IA.

This work also guided OIF to initiate two follow-on co-packaging projects: External Laser Small Form Factor Pluggable (ELSFP) Project, announced in May 2021, and the 3.2T Module Project, announced in March 2021.

“OIF is leading industry discussion on this critical dense integration technology,” said Jeff Hutchins, Ranovus and OIF Board Member and PLL Working Group – Co-Packaging Vice Chair. “This framework IA provides the industry with a foundation for developing interoperable energy efficient co-packaged solutions.”

“Co-packaging represents a significant change to the way high-performance communications ASICs are packaged today,” said Technical Editor of the Co-Packaging Framework IA, Kenneth Jackson, Sumitomo Electric. “This Framework document addresses many of the issues that initially challenged this new architecture and narrows the scope of achievable solutions. This is precisely what OIF excels at…identifying a gap and collaborating on a path forward towards interoperability.”

Earlier this month, OIF experts led a public webinar, “Co-Packaging Standardization Progress,” discussing the co-packaging standardization efforts that are in progress and addressing implementation challenges, including electrical channels, external lasers, optical connectivity, packaging, etc. In partnership with Lightwave, the event featured talks from industry-leading experts at Intel, Cisco, Ranovus, Sumitomo Electric and TE Connectivity.

OIF Completes Coherent Common Management Interface Specification (C-CMIS) Implementation Agreement for Management of Digital Coherent Optics (DCO) Modules

Initial release is focused on supporting 400ZR

Fremont, Calif.—March 3, 2020OIF, where the optical networking industry’s interoperability work gets done, today announced the completion of the Coherent Common Management Interface Specification (C-CMIS) Implementation Agreement (IA). This IA serves as an extension to the CMIS (QSFP-DD/OSFP/COBO) management specification, specifically targeting DCO modules.

“The C-CMIS IA is an important part of the developing 400ZR ecosystem,” said Ian Betty, Ciena and OIF Board Member. “It defines additional management registers, and monitors, together with new functionality, mechanisms, or behaviors, as needed.”

Augmenting the existing CMIS specification which focused on addressing direct detect client optics, the C-CMIS IA provides register definition for coherent modules in pages and parameters that were previously reserved. Users that have previously implemented software to manage optical modules using CMIS will be able to quickly add support for these coherent pages and parameters. This release of the C-CMIS IA is targeted at the 400ZR application.

The technology and complexity of coherent modules requires additional monitoring parameters for use in field applications. This additional monitoring is primarily focused on Forward Error Correction (FEC) monitoring and optical/analog monitoring including items like Chromatic Dispersion, Differential Group Delay and Electrical Signal to Noise Ratio (eSNR). The C-CMIS IA provides specifications to monitor the standard parameters in a normative manner while taking advantage of the flexibility of the CMIS specification to monitor any additional proprietary parameters.

“The current IA is focused on supporting the OIF 400ZR IA, which supports a single data path with eight-lane host electrical interface for a 400GBASE-R PCS signal and a single-lane 400G coherent media interface (with a new signal format called 400ZR),” explained Betty. “However, we expect future versions to include more complex Metro modules and may even extend these management features to other form factors.”

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.
