SEOUL / GLASGOW—LESSENGERS, a provider of optical components based on its patented “direct optical wiring” (DOW) technology, announced that its new 800G transceiver product (800G OSFP SR8) would begin volume production in the fourth quarter and begin shipping to customers.
DOW is a polymer-based air-cladded waveguide technology that is particularly useful for optical interconnects in the data center and high-performance computing environments.
DOW connects active photonic devices, such as laser diodes or photodiodes, directly to the optical fiber, providing high-density and high-speed optical signal connectivity between switches, servers, and other devices within the data center or HPC clusters.
“The use of DOW technology enables us to achieve high-performance and low-noise optics by its nature, allowing us to streamline the production process flow with complete automation,” said Chongcook Kim, CEO of LESSENGERS.
LESSENGERS said this capability enables several operational efficiencies and economic benefits:
· No active alignment – cost-competitive optical coupling
· No use of multi-channel lens assembly – near-zero optical crosstalk
· No air gap – dramatically lower reflection noise
· High degree of freedom in heat sink design – much lower junction temperature
“Demand for optical connectivity in AI Clusters is accelerating innovation,” said Dr. Vladimir Kozlov, CEO and founder of LightCounting. “New pluggable and co-packaged optical engine designs rely on high-density parallel connectivity, which needs new packaging and fiber-coupling methods. Direct optical wiring, developed by LESSENGERS, is a great example of such new approaches.”
