ECOC 2023: LESSENGERS 800G transceiver goes into production
Created October 4, 2023
Technologies and ProductsLESSENGERS Inc., announced at ECOC 2023 that its new 800G transceiver product (800G OSFP SR8), based on the company’s Direct Optical Wiring (DOW), will begin volume production in the Q4 2023 and begin shipping to customers. DOW is a polymer-based air-cladded waveguide technology that is particularly useful for optical interconnects in the data centre and high-performance computing environments.
DOW connects the active photonic devices such as laser diodes or photodiodes directly to the optical fibre, providing high-density and high-speed optical signal connectivity between switches, servers, and other devices within the data centre or HPC clusters. LESSENGERS says this capability enables several operational efficiencies and economic benefits, including:
- 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
The company says these attributes make the 800G OSFP SR8 and other products for high-speed active optical cables and transceivers high-performance, highly reliable and cost compelling.
“We are proud to announce the volume production of DOW-based 800G AOCs and transceivers,” said Chongcook Kim, CEO at LESSENGERS. “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.”
“Demand for optical connectivity in AI Clusters is accelerating innovation,” commented Dr. Vladimir Kozlov, CEO and Founder of LightCounting. “New designs of pluggable and co-packaged optical engines rely on high density parallel connectivity, which need new packaging and fibre-coupling methods. Direct optical wiring, developed by LESSENGERS, is a great example of such new approaches.”
