800G OSFP transceiver enters volume production

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. 

This capability enables several operational efficiencies and economic benefits, such as:

• 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

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.

“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.”

“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.”

LESSENGERS is participating at the European Conference on Optical Communications (ECOC) in Glasgow (October 2-4).
