OIF addresses the need for accelerated optical standards, interoperability efforts
As the demands from AI have created new bandwidth expectations, the Optical Interoperability Forum (OIF) realizes that it has to respond to new demands for industry interoperability in near real time. This was reflected in the OIF’s Next Generation CEI-448G Framework Document, released at its recent Q4 2025 Technical and MA&E Committees Meeting. OIF’s CEI-448G Framework Document defines the application spaces, technical challenges and potential solution paths for electrical interfaces operating at 448 Gbps per lane.
During this podcast, we talked to two optical industry veterans about OIF’s recent CEI documents and its expectations for OIF’s first quarter 2026 Technical and MA&E Committees meeting at the OFC show in March:
Nathan Tracy, President of OIF
And
Cathy Liu, board member of OIF
