OIF, the global industry forum accelerating market adoption of advanced interoperable optical networking solutions, has announced the start of two new projects – 800G Coherent and Co-Packaging Framework, availability of a new FlexE for 400ZR white paper, and newly elected board members/positions and working group representatives. These activities and elections took place at the Q420 Technical and MA&E Committee meetings held virtually November 2-November 6, 2020.
NEW PROJECTS
800G Coherent
The scope of the 800G Coherent project is to define interoperable 800G coherent line specifications for campus and DCI applications. The resulting Implementation Agreement (IA) will:
- Define single-lambda 800G coherent line interfaces for two applications
- Amplified, single span, DWDM links up to 80-120km
- Unamplified, fixed wavelength links of 2-10km
- Support Ethernet client(s) (minimum 100GE) up to 800G aggregate bandwidth
“The next standardized coherent rate beyond 400ZR will be technically challenging with many factors to be considered,” said Tad Hofmeister, Technical Lead, Optical Networking Technologies at Google and OIF Vice President. “With the 800G Coherent IA, OIF is in a unique position to take a leadership role in defining interoperable 800G coherent line interfaces for various applications.”
Co-Packaging Framework IA
The Co-Packaging Framework IA, announced on November 10, 2020, will study the application spaces and relevant technology considerations for co-packaging of communication interfaces with one or more ASICs. A primary objective of this specification is to identify new opportunities for interoperability standards for possible future work at the OIF or other standards organizations. Upon completion, the work will be summarized in a Framework IA.
White Paper
A new OIF white paper addressing 400ZR applications requiring multiplexing of lower rate Ethernet signals (e.g., 100GE) and how to leverage FlexE for this service multiplexing is now available.
The OIF 400ZR IA includes mapping of 400G Ethernet signals as defined in IEEE 802.3, but not lower rate services such as 100G Ethernet. This white paper describes utilizing the OIF FlexE Implementation Agreement multiplexing of lower service rates, such as 100G and 200G Ethernet to a 400G frame that can be carried by 400ZR devices. Example profiles are provided to guide interoperability in common scenarios.
