Two of the hot items at OFC22 were faster pluggable transceivers (800G and even 1.6T in the future) and Co-Packaged Optics (CPO), says David Chen, AVP, Strategic Marketing & Standard Office for Transceivers, AOI.
There was a lot of activity at the OIF booth regarding CPO, external laser source modules -- all related to COBO's current working groups. This video includes a diagram showing the evolution of COBO and NPO technologies.
