Lessengers Announces Industry-First Partially Retimed 800G Optical Transceivers for AI/ML Workloads

LESSENGERS announced a comprehensive portfolio of 800G optics designed for AI/ML workloads in hyperscale data centers. Lessengers is adding partially retimed capability to its 800G transceiver product portfolio, which in one product entails an integrated DSP chip on the transmitter side.

This capability will enable a wide range of interoperability with other pluggable transceivers and lower power consumption due to the use of a half retimer.  At OFC 2024, the company will highlight the launch of its industry-first 800G OSFP Linear Receive Optical Transceiver.

LessengersTM AI/ML product now features the following integrated retimer electronics along with existing fully retimed optics:

The 800G Linear Receive Optical Transceiver now offers:

All of Lessengers products are based on the company’s patented DOW technology, which is a polymer-based air-cladded waveguide technology that is particularly useful for optical interconnects in the data center and high-performance computing environments.

“Demand for 800G SR8 transceivers exceeded all expectations in 2023 and more than 3 million units of these modules will be shipped in 2024,” commented Dr. Vladimir Kozlov, CEO and founder of LightCounting Market Research. “Improvements in power efficiency of optical transceivers are critical for scaling AI clusters from tens of thousands of GPUs now to hundreds of thousands in 2025-2026. All solutions, including LPO and HALO designs, are being evaluated by the leading customers for future deployments.”

“We are excited to demonstrate at OFC our latest advances in the field of 800G optics, which will be crucial to improving the processing of AI/ML workloads,” said Chongcook Kim, CEO at Lessengers.  “We look forward to working with our partners and customers throughout the hyperscale and supercomputing ecosystems in order to realize these gains.”
