Why it matters

Lightmatter is testing whether photonics can move from promising components into open, manufacturable AI racks. The switch is a production-validation platform; the XPU tray remains a proof of concept, so neither yet demonstrates customer deployment or volume production.

A slim Lightmatter photonic-switch tray sits in an open rack beside a separate XPU proof-of-concept tray in a rain-lit validation lab.

Lightmatter founder and CEO Nicholas Harris brought two rack-scale photonics systems to the Open Compute Project summit in San Jose on October 12th: a 204.8-terabit-per-second switch tray built with Flex, and a separate four-accelerator compute tray designed to demonstrate optical connections inside an open server architecture.…
