JOEL WILLIAMS, NEWS EDITOR [email protected]SANTA CLARA, Calif., March 21, 2025 — NVIDIA’s planned commercialization of its Spectrum-X (Ethernet) and Quantum-X (InfiniBand) photonic switches signals a shift in the industry’s copper bedrock. According to PhotonDelta’s ecosystem manager Abdul Rahim, it could mark the beginning of “the golden age of silicon photonics.” That a company of NVIDIA’s scale is introducing silicon photonics-based co-packaged optics (CPO) solutions is indicative of the technology’s maturity level — reaching a point where it is both commercially viable and technically necessary, said René...Read full articleRelated content from Photonics MediaArticlesNVIDIA Debuts Silicon Photonics Switches for AI Data CentersNVIDIA has unveiled a pair of co-packaged silicon photonics networking switches that it says will allow AI facilities to connect millions of GPUs across sites while drastically reducing energy...Photonics.com 3/19/2025PhotonDelta Names Eelko Brinkhoff CEODutch photonics consortium PhotonDelta has named Eelko Brinkhoff CEO in a move that will take effect Feb. 19, 2024.
