Lightmatter Joins NVIDIA NVLink Fusion and Powers Next-Generation AI Infrastructure with Photonic Interconnects

Lightmatter, the leader in photonic (super)computing, today announced it has joined the NVIDIA NVLink Fusion ecosystem to accelerate the deployment of high-performance optical connectivity for AI infrastructure. Through this collaboration, Lightmatter will deliver Co-Packaged Optics (CPO) and Near-Packaged Optics (NPO) products that are compatible with NVIDIA’s optical and SerDes technologies.

By adapting Lightmatter’s bi-directional optical link architecture for NVIDIA’s optical and electrical technology, Lightmatter is creating a unified platform for semi-custom AI factories while reducing fiber and connector requirements by 50%. This approach enables customers’ semi-custom XPUs to connect with NVIDIA switch silicon through Lightmatter’s CPO and NPO products, creating seamless high-bandwidth connectivity for chips from various suppliers within the NVLink Fusion ecosystem.

“This is what the next era of AI infrastructure looks like," said Nick Harris, Ph.D., founder and CEO of Lightmatter. "By integrating Passage CPO solutions with NVIDIA's NVLink Fusion architecture, we are combining the industry's most advanced AI platform and the world's leading interconnect to unleash generations of leading frontier AI models.”
