Its shipped and announced products are VCSEL-based multimode: 200G SR4, 400G SR4 and SR8, 800G 2xSR4 and SR8 including partially retimed variants with an integrated DSP on the transmit side, a 1.6T OSFP 2xSR4 announced 2025-03-31, plus active optical cables and a 200G optical engine. The founder previously led optical device R&D teams at Samsung Electro-Mechanics and LG Innotek and holds a PhD from POSTECH. On 2026-03-17 it expanded an existing partnership with POET Technologies to jointly develop a 1.6T 2xDR4 module combining POET optical engines with DOW, with samples targeted for the second quarter of 2026. An independent optical-components analyst note published 2026-07-28 assesses that Lessengers will need a large manufacturing partner to scale transceivers and that its likelier route is licensing DOW to a major manufacturer.","sub_category":"Optical & photonic interconnect","signals_total":3,"url":"https://www.frontiertechintelligence.com/companies/lessengers","title":"Lessengers · ai core, Pohang, North Gyeongsang, South Korea · scores, facts and signals · Frontier Tech Intelligence","description":"Lessengers develops and produces optical transceiver modules, including 100G, 800G, and 1.6T products for AI, hyperscale, and data-center networks.
