09:06 AM EDT, 03/20/2025 (MT Newswires) -- POET Technologies Inc. ( POET ) , a player in the design and implementation of highly-integrated optical engines and light sources for artificial intelligence networks, was at last look up 0.6% in US premarket trade on Thursday after announcing it has fulfilled orders from three global customers for samples of its advanced optical transmit engines.

The company in a statement announced that it has shipped final design samples of its POET Infinity transmit product line for 400G and 800G applications to three major technology leaders. The products include 400G FR4, 800G 2xFR4 and 800G DR8 transmit formats, all assembled at its high volume production facility in Malaysia.

Thursday's statement noted the FR4 optical engines incorporate the multiplexer and can be paired with POET receiver engines for a highly integrated pluggable transceiver. POET's customers have designed and are building pluggable transceivers using a two-chip solution, i.e., one transmit chip and one receive chip for 400G and three-chip solution for 800G. The receive optical engines have already been qualified and the availability of the transmit engine samples will allow the shipment of completed modules to end customers for qualification, with production orders expected in the second half of 2025.
