Nvidia outlines plans for using light for communication between AI GPUs by 2026 — silicon photonics and co-packaged optics may become mandatory for next-gen AI data centers
The extreme demands of passing communication between ever-growing clusters of AI GPUs is fueling a move towards using light for communication across the networking layers. Earlier this year, Nvidia outlined that its next-generation rack-scale AI platforms will use silicon photonics interconnects with co-packaged optics (CPO) for higher transfer rates at lower power. At the Hot…
