POET Technologies has announced a partnership with South Korea-based Lessengers to co-develop a next-generation 800G DR8 optical transceiver targeted at AI and hyperscale data center applications. The solution will integrate POET’s Infinity™ transmit and receive optical engines with Lessengers’ Direct Optical Wiring (DOW) technology, aiming to deliver a compact, power-efficient, and cost-effective transceiver platform.
The 800G DR8 architecture will feature POET’s highly integrated photonic and electronic components, designed using its Optical Interposer™ platform. Lessengers will incorporate POET’s optical engines into its transceivers, leveraging DOW’s direct optical coupling to eliminate fiber arrays and simplify assembly. Sample units are expected to be available for customer evaluation in the second half of 2025. The companies are showcasing their technologies side-by-side at OFC 2025 in San Francisco.
This collaboration extends POET’s global reach and strengthens its position in the high-speed optical interconnect market. It also brings together complementary innovations in photonic integration and optical packaging that address the performance, efficiency, and cost challenges facing hyperscale and AI infrastructure operators.Key Points:
• POET and Lessengers are co-developing an 800G DR8 optical transceiver for AI and hyperscale markets.
• Transceiver will integrate POET Infinity™ optical engines and Lessengers’ Direct Optical Wiring (DOW) tech.
• DOW removes fiber arrays to simplify packaging and reduce cost.
• Customer samples expected in H2 2025.
• Both companies are exhibiting at OFC 2025: POET at Booth 5315.
“POET’s production-ready optical engines provide Lessengers with a high-quality component that allows us to bring more value to our transceiver customers,” said Taeyong Kim, Chief Marketing Officer at Lessengers.
