In case people missed Adrian's response to Rainer on Reddit here it is:

Hi Rainer,
This excerpt is from the FAQ of Oct. 28 published on the POET blog (https://poet-technologies.com/blog/2022-oct-28.html). It explains what "released to production" means, what products have been released and what the next steps are as customers take time to evaluate the final "frozen" designs:
"POET will release four products into production by the end of 2022. Those products are: 100G CWDM4 TX, 100G CWDM4 RX, 200G RX, and 400G RX. And then there will be another four products released for production in the first half of 2023. The status 'Released to Production' means that POET has frozen the design (usually in connection with a module maker after all the required or requested tweaks have been made). The module maker then orders POET Optical Engines to include in its initial samples that go to its customers for evaluation. Then there is qualification, then purchase orders. During that period there will be some production of inventory and revenue associated with that work. Meanwhile, our customer engagements and design-in activities continue to gain momentum, with at least two customers in China to get into production early next year. And we have multiple design-in activity with other module customers."

I will work on getting you an update on the status of the products that have been released to production when everyone is back in the office this week. I expect additional announcements will be made in January that may provide a satisfactory update.
