From Sept. 2023:

In cooperation with customer Luxshare-ICT, POET along with its joint venture partner Super Photonics Xiamen (SPX), will show a live demonstration of the performance of Luxshare's 800G OSFP transceiver that incorporates POET’s 800G Rx optical engine.

POET and SPX will also present additional live demonstrations of optical engines for 800G, 400G, and 200G transceivers operating over a wide temperature range and 2km to 10km of single mode fibre transmission. The aim of the demonstrations of linked optical engines on both the transmit and receive ends of the fibre is to highlight the end-to-end performance and product readiness of POET’s optical engines.

Mo Jinyu:

“We are already seeing significant customer interest to test and use our engines in transceivers from 100G to 800G and even 1.6T speeds."

"POET’s products that are assembled and sold in China by SPX.”

This may not be an accurate observation, but it does seem as though we progress from demo, to customer, to production somewhat quicker than previously.  Possibly this is a result of the quality that POET is creating along with the size/seriousness of the customer's needs, along with their ability to envision multiple uses.
