Passage Interconnect by Lightmatter — Product Research | aVenture

Passage is Lightmatter's photonic interconnect platform for AI supercomputers. It uses 3D vertical integration to place I/O across the entire die area, scaling bandwidth density with die area rather than being limited to shoreline edges.

The platform spans pluggable, on-board, co-packaged, and interposer-co-packaged form factors, with products such as the L200 and M1000 delivering tens of terabits per second of aggregate bandwidth for frontier-scale AI training clusters.
