POET teams with Lessengers to develop 800G DR8 transceivers for AI and hyperscale markets
POET Technologies Inc of Toronto, Ontario, Canada — designer and developer of the POET Optical Interposer, photonic integrated circuits (PICs) and light sources for the hyperscale data-center, telecom and artificial intelligence (AI) markets — has partnered with Lessengers Inc of Seoul, South Korea — which provides optical components based on its patented direct optical wiring (DOW) technology — to offer a differentiated 800G DR8 transceiver. The transceiver will include POET’s transmit and receive optical engines and Lessenger’s Direct Optical Wiring (DOW) technology for a cost-effective solution for AI and hyperscale data center applications.
POET will supply the highly integrated POET Infinity transmit and receive optical engines configured in an 800G DR8 architecture, which includes electronic and photonic components.
Lessengers expects to have transceiver samples ready for its customers to review in second-half 2025.
“We’re thrilled to continue our growth in the industry through a co-development arrangement with a likeminded and truly inventive company,” comments POET’s chief revenue officer Raju Kankipati.
“POET’s production-ready optical engines provide Lessengers with a high-quality component that allows us to bring more value to our transceiver customers,” says Lessengers chief marketing officer Taeyong Kim. “POET offers a complementary technology to Lessengers’ direct optical coupling that saves on costs and improves efficiency.”
At the Optical Fiber Communications Conference & Exposition (OFC 2025) in San Francisco, CA, USA (1–3 April), the two companies’ booths are situated next to each other: POET in booth 5315 and Lessengers in booth 5221.
