Taken from the recent ADVA NR.  I think they are shipping Beta samples to ADVA with production for 2H 2023.   Would be nice if POET didn't just assume everyone remembers in fine detail what they said a few months ago.  PR needs to improve in this respect!

POET’s multi-engine chips incorporate multiple instances of industry standard 100GBASE-CWDM4, for 2km applications, and 100GBASE-LR4, for 10km applications, transmit and receive functionalities on a single optical engine. The Company’s 100GBASE-LR4 optical engines are the industry’s first implementation of chip-on-board solutions for the 100G LR4 market. The hybrid integration of lasers and photodiodes, monolithic integration of optical MUX and DMUX and the passive alignment of components on POET’s Optical Interposer platform provides a unique and differentiated solution to enable high-density network connectivity.

POET has successfully demonstrated 10km operation of 100G LR4 optical engines in its Shenzhen Lab and plans to ship beta samples to ADVA in Q1 2023 with production targeted in the second half of 2023.
