POET and Lessengers Jointly Develop 1.6T Optical Transceiver Module
POET Technologies and Lessengers announced the joint development of a 1.6T 2xDR4 optical transceiver module designed for next-generation AI clusters and hyperscale data center networks. The effort combines POET's highly integrated optical engines, built on its Optical Interposer platform, with Lessengers' Direct Optical Wiring technology, creating a scalable architecture for high-density optical interconnects required by emerging AI infrastructure. The 1.6T 2xDR4 transceiver will utilize POET's optical engines to integrate lasers, modulators, photodiodes, and passive optical components on a compact photonic platform. Lessengers' DOW technology provides a flexible optical wiring approach that enables efficient optical routing between photonic devices and fiber interfaces, helping simplify packaging while supporting high-bandwidth optical connectivity.Samples of the 1.6T 2xDR4 transceiver module are targeted for availability in Q2 2026, aligning with the anticipated industry transition toward higher bandwidth optical links for AI-driven data center networks.
