Lambda, the Superintelligence Cloud, announced today that it is among the first AI infrastructure providers to adopt NVIDIA’s silicon photonics–based networking technology.

As AI models scale to hundreds of thousands of GPUs and beyond, the network fabric connecting them has become just as critical as the GPUs themselves. Traditional networking architectures are struggling to keep pace with this exponential growth. NVIDIA’s co-packaged optics (CPO) offers a breakthrough, addressing bandwidth and power efficiency constraints at the heart of next-generation AI factories.

“NVIDIA Quantum-X Photonics is the foundation for high-performance, resilient AI networks. It delivers superior power efficiency, improved signal integrity, and enables AI applications to run seamlessly in the world’s largest datacenters,” said Ken Patchett, VP of DC Infrastructure at Lambda. “By integrating optical components directly next to the network switches, we believe our customers can deploy AI infrastructure faster while significantly reducing operational costs—critical as we scale to support frontier AI workloads.”

According to NVIDIA, its Photonics technology delivers 3.5× better power efficiency, 5× longer sustained application runtime, and 10× greater resiliency compared to traditional pluggable transceivers. These improvements allow AI infrastructure to achieve higher compute density per watt and improved network reliability, accelerating both training and inference.

Designed for the era of real-time AI, NVIDIA Photonics also simplifies networking architecture with fewer components to install and maintain. Lambda continues to expand its scalable AI infrastructure offerings, supporting enterprises, research institutions, and startups in building multi-site, large-scale GPU AI factories.

“AI factories are a fundamentally new class of infrastructure—defined by their network architecture and purpose-built to generate intelligence at massive scale,” said Gilad Shainer, Senior Vice President of Networking at NVIDIA. “By integrating silicon photonics directly into switches, NVIDIA Quantum-X silicon photonics networking switches enable the kind of scalable network fabric that makes massive-GPU AI factories possible.”

This announcement further strengthens Lambda’s collaboration with NVIDIA. Lambda recently earned NVIDIA Exemplar Cloud status, recognizing its consistent performance in large-scale training on NVIDIA Hopper GPUs. Over the past decade, Lambda has received six NVIDIA awards, reinforcing its position as a trusted partner within the NVIDIA ecosystem.
