On Tuesday at the GTC conference, Nvidia CEO Jensen Huang announced two silicon photonics switches for high speed networking in data centers. Nvidia is heavily invested in optical networking, but the power requirements for each connection can quickly add up in a large-scale data center.

“AI factories are a new class of data centers with extreme scale, and networking infrastructure must be reinvented to keep pace,” Huang said. “By integrating silicon photonics directly into switches, Nvidia is shattering the old limitations of hyperscale and enterprise networks and opening the gate to million-GPU AI factories.”
