World's first light-powered neural processing units (NPUs) could massively reduce energy consumption in AI data centers

Lightmatter unveiled the Passage M1000 optical interposer and Passage L200 co-packaged optics this week, showcasing them at the Optical Fiber Conference in San Francisco.
The interconnects address the increasing demand for chip-to-chip bandwidth driven by denser AI deployments and bandwidth scaling impediments.
Passage M1000 targets XPUs and multi-die switches, using light to transfer data and supporting 256 fibers, while Passage L200 is a 3D CPO product for XPUs and switch silicon designs.
Lightmatter claims the M1000 supports up to 114 Tbps of optical bandwidth, and the L200 promises 32 Tbps of bidirectional bandwidth, which is a 5 to 10x improvement.
Lightmatter plans to ship the Passage M1000 in the summer of 2025, manufactured by GlobalFoundries, and the Passage L200 in 2026, offering improved AI performance scaling.
