POET and Lessengers to Launch 1.6T 2×DR4 Transceivers with Q2 2026 Samples
POET Technologies and Lessengers announced a joint development of a 1.6T 2×DR4 optical transceiver module combining POET’s Optical Interposer platform with Lessengers’ Direct Optical Wiring technology. Samples are slated for Q2 2026 launch, targeting a market forecast of over 125 million DR8 units through 2031.
1. Partnership Overview
POET Technologies and Lessengers are collaborating to develop a 1.6T 2×DR4 optical transceiver module designed for next-generation AI clusters and hyperscale data centers. This joint effort leverages the strengths of both companies to meet rising bandwidth demands in AI networks.
2. Technical Integration and Benefits
The module integrates POET’s Optical Interposer platform, which combines lasers, modulators, photodiodes, and passive optical components on a compact photonic engine, with Lessengers’ Direct Optical Wiring technology to streamline optical routing and simplify module packaging while maintaining high bandwidth.
3. Market Prospects and Timeline
Samples of the 1.6T 2×DR4 transceiver are scheduled for Q2 2026 availability, aligning with expected industry shifts toward higher bandwidth links. The market for similar 1.6T DR8 modules is forecasted to exceed 125 million units between 2027 and 2031.
