How Optical Circuit Switching (OCS) Enables Large-scale GPU Clusters

For AI/ML training clusters, the Lumentum R300 OCS enables optical connectivity across the rack, allowing you to replace or bypass traditional spine switches. This creates dynamic, high‑bandwidth paths for GPU‑to‑GPU communication in large‑scale AI systems while significantly reducing network power consumption. The solution integrates seamlessly with Marvell’s optical connectivity portfolio and the RELIANT™ interconnect telemetry platform, providing scalable, efficient, and intelligent network fabric control for next‑generation GPU clusters.
