Lightmatter has joined the NVIDIA NVLink Fusion ecosystem, bringing its photonic interconnect technology to AI infrastructure for hyperscalers. The company's Passage interconnects and Guide light engines are designed for frontier-scale training with up to 64 Tbps aggregate bandwidth. Additionally, Lightmatter announced a world-first 16-wavelength bidirectional optical DWDM link, claiming an 8x leap in fiber bandwidth density. This signals growing adoption of silicon photonics for AI scale-up networks, addressing the electrical I/O bottleneck where chips run out of edge space. Source: Lightmatter IR snapshot.
