Photonic Fabric™: Optical Scale‑Up for Next‑Generation AI Clusters
Next‑generation AI clusters demand unprecedented reach, bandwidth, ultra‑low latency, and energy efficiency. Photonic Fabric™ is an optical interconnect purpose‑built for AI scale‑up and memory transactions—delivering lower XPU‑to‑XPU latency and enabling multi‑rack optical scale‑up at 4× greater energy efficiency than copper.
Photonic Fabric™ addresses the memory wall with fabric‑attached pooled memory, supporting HBM‑cached DDR as disaggregated, shared memory across the cluster. By reducing data‑movement energy and improving GPU utilization, it enables 2–3× more compute within the same power footprint—unlocking higher performance at scale without increasing power budgets.
