From our friends across the pond, IEEE 802.3df has been ratified, 800GbE set to go --

the initial IEEE 802.3dj 1.6T and 200G per lane technology adoption timelines may be delayed. Reasons include IEEE 802.3dj schedule delays, a focus on deploying 800G for AI/ML

A hot topic among OFC attendees was alternative paths to 1.6T. Instead of doubling the number of bits, the number of electrical lanes can be doubled from 8 to 16 using OSFP-XD technology. OSFP-XD offers 1.6T density with 16 lanes of 100G and the potential for 3.2T density with 16 lanes of 200G. Using 16 lanes of 100G would be an option for hyperscalers.

Last month, the IEEE ratified 802.3df, the 800G Ethernet rate, 100G electrical lane architecture standards. Just as with 400G, the industry is rallying and converging quickly on the technology now that standards are completed. Vendors are rushing to demonstrate they are compliant with the 100G lane architecture.
