Lessengers Pluggable NPO Optical Engine Featured at AI Infra Summit 2025

‍

September 11, 2025– Lessengers’ linear drive 800G near-packaged optics (“NPOs”) optical engine was featured in Alphawave Semi’s demonstration at the AI Infra Summit 2025, highlighting a breakthrough in serviceability for on-board optics.

‍

Traditional on-board optics raise a critical concern: how to repair or replace a component if it fails.

Lessengers addresses this challenge with a socket-type, pluggable optical engine design that allows straightforward replacement, enabling easier maintenance and reducing system downtime.

Key Features of the Lessengers 800G NPO optical engine:

• Detachable, socket-type design for repairability and serviceability
• 8 × 112G PAM4 electrical interfaces
• Ultra-low energy consumption (<7 pJ/bit)
• Pluggable optical interface with standard 2×MT12 fiber
• Immersion cooling readiness
• Proven BER stability at 100 m reach

‍

By combining high-performance optical connectivity with practical serviceability, Lessengers is demonstrating that NPO is ready for scalable, real-world AI/ML infrastructure. The demo was presented live at the Alphawave Semi's booth, further validating the potential of NPO and optical I/O as essential technologies for the future of AI infrastructure.
