Now that 50 Gbps electrical rates are ramping in the industry, it's the perfect time to understand the 72 116 Gbps common electrical interface (CEI) standardization performance levels coming from the OIF's next update to their CEI-112G Implementation Agreements. OIF members and industry experts will provide an update on the 112 Gbps challenges and the tradeoffs considered and debated to reach this point in maturity. In addition, now that the CEI-112G standards work is wrapping up, the OIF is turning it's attention to knowledge building on the challenges that an electrical rate at 224 Gbps will bring and ideas to address these challenges, as well as initial ideas and proposals on how CEI-224G ought to be standardized. We know the industry will need to move to optical rates of 1.6Tbps and electrical interfaces and standards such as CEI-224G will be important to enable 1.6Tbps optics and related networks.
