Hi Ted,
You wrote about the mysterious PIC at 200g per lane.
“We are talking about something that has never been done before: 4x200gpbs. It could take a few more months, or it could take a few more years, or it may not be possible to do.”
Look up Poet Technologies, the demoed this PiC with Insiga at the CIOE in September/24……also working with Mitsubishi on 400g per lane for 3.2T optical engine. They are getting a lot of interest because they have products and can customize to customer needs quickly with their Optical Interposer platform.

“Discussions. Not active partnerships where products are BEING designed.. Discussions. Where is the evidence that they are actively working together on customized PIC designs, and creating demos? “
Poet has you covered here too. Look up their partnerships .
