Dear >400GbE Study Group Participants,
We ran out of time during my presentation slot to give everyone an opportunity to ask questions and make comments.
Cedric Lam had an important projection to share, which is that 800G duplex fiber modules will ship in 2022.
In his presentation, Ali Ghiasi pointed out that 800GbE standards work started in the Ethernet Technology Consortium (ETC) before the start of the >400GbE SG. Brad Booth, ETC Chair, and Rob Stone, ETC Technical WG Chair, informed me that
this started in 2019.
So my predictions are crumbling before the ink is dry on the presentation, and the 800GbE table entries need the below update.

As Brad cautioned us on the call, and Cedric did similarly after the call, predictions based on the past should be taken with a grain of salt as new trends and dependencies are rapidly developing. I will redouble my efforts and more carefully
study the crystal color energy wheel to find a more reliable color.
