Browsing the topics beings discussed at this years OFC, the section "Advanced Prototyping, Packaging and Integration" has a Google employee speaking about "State of Art of 800G/1.6T for Datacom and Coherent and Outlook of 3.2T".
Given the Edward connection, it is an interesting topic to be speaking about.
