any idea what the prototype might be? Hopefully a 400G transceiver (see any poet-technologies.com presentation since about 2018). Similar 100G designs corresponding to the various MSA-defined types would be nice too (FR, LR etc..)
testing more than one? Wafer scale implies you are producing a wafer and testing maybe hundreds of prototypes at a time.
how many hours? no idea. The tier 1 would specify for us, and they would take direction from their customer.
sales agreements: I have no insight. I assume you would begin drafting before longevity testing is finished.
is each prototype a vertical? No. Only prototypes that are in different verticals than previous prototypes ;) Seriously, many transceiver prototypes might all be in the same datacenter vertical. But POET has indicated they would begin pursuing 5G, PON and sensing verticals as soon as tier 1 work is in production.
