NVIDIA's Spectrum-X silicon photonics Ethernet technology is now in full
production. The next-generation Spectrum-X switch uses co-packaged optics (CPO)
and supports the Vera Rubin platform for data-center horizontal scaling and
cross-region AI factory deployments. NVIDIA says Spectrum-X can deliver 5x
network energy efficiency versus networks using traditional transceivers, 5x
improvement in AI uptime, and 1.3x faster deployment.
