POET Technologies Inc. announced that it has developed multi-engine 100G CWDM4 and 100G LR4 chip-on-board solutions for its lead customer, ADVA Optical Networking SE. ADVA will use POET's multi-engine transmit and receive chips in an innovative pluggable solution that packs the functionality of four independent 100Gbit/s interfaces into a single QSFP-DD housing. 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 First Quarter 2023 with production targeted in the second half of 2023.

According to LightCounting's April 2022 report, the market opportunity for 100G CWDM4 and LR4 pluggable transceivers will continue to remain strong at an average size of $700 million annually from 2023 to 2027.
