Chip companies are investing in photonic interconnects to sidestep electrical bandwidth limits that degrade AI inference at scale. Optical connections between GPU clusters offer 3–10x higher throughput than copper signaling, cutting model serving latency in large deployments.
NVIDIA, Intel, and startups are integrating photonic I/O into next-gen AI accelerators. As inference clusters grow and per-token latency budgets tighten, light-based signaling moves from research curiosity to production necessity for hyperscale inference ops.
