Lessengers Unveils Industry-First 800G Optical Transceivers for AI/ML Workloads at OFC 2024

Mar 19, 2024: Lessengers Inc., a pioneer in optical components leveraging its patented “direct optical wiring” (DOW) technology, has announced the launch of a comprehensive lineup of 800G optics tailored for AI/ML workloads in hyperscale data centers. This innovation marks a significant milestone in optical communication, with Lessengers introducing partially retimed capability to its 800G transceiver product portfolio, including an integrated DSP chip on the transmitter side.

At the Optical Fiber Communications Conference (OFC) 2024 in San Diego, Lessengers will showcase its groundbreaking 800G OSFP Linear Receive Optical Transceiver, setting new benchmarks in optical networking.

The 800G Linear Receive Optical Transceiver boasts several key features:

• Lower Power Consumption: Consuming less than 9 W for an 800G (2 × SR4) OSFP, the transceiver offers enhanced energy efficiency.
• Compliance: IEEE 802.3 and CMIS 5.0 or later compliant, ensuring compatibility with industry standards.
• PAM4 Interfaces: Supporting 8 × 112 Gb/s PAM4 on both the electrical host receiver and optical line transmitter interfaces.
• Integrated Retimer Chip: Featuring a half retimer chip integrated in the transmit path, enhancing signal retiming and equalization.

These advancements are underpinned by Lessengers’ proprietary DOW technology, a polymer-based air-cladded waveguide technology ideal for data center and high-performance computing environments.

Dr. Vladimir Kozlov, CEO and founder of LightCounting Market Research, commented, “Demand for 800G SR8 transceivers exceeded all expectations in 2023, and more than 3 million units of these modules will be shipped in 2024. 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.”

Chongcook Kim, CEO at Lessengers, expressed excitement about the company’s latest advancements, stating, “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. We look forward to working with our partners and customers throughout the hyperscale and supercomputing ecosystems to realize these gains.”

Lessengers invites attendees to visit their booth, number 5200, at the San Diego Convention Center from March 26 to 28, 2024, during the Optical Fiber Communications Conference (OFC).
