Lightmatter has announced the Guide DR laser NIC, a new product to support co-packaged optics (CPO) scale-up source. This launch complements Lightmatter's existing photonic interconnect platform, which includes the Passage and Guide product lines. Company materials highlight breakthroughs such as a world-first 16-wavelength bidirectional optical link and the Passage M1000 3D photonic superchip, delivering up to 114 Tbps across a 4,000 mm² footprint source. The Guide DR laser NIC is positioned to address bandwidth bottlenecks in AI training clusters, targeting 100,000+ GPU deployments. This signals Lightmatter's continued product expansion and potential for increased adoption among hyperscalers, though no customer commitments have been disclosed.
