300x300 Optical Circuit Switch (OCS)

R300

OCS300

The Lumentum R300 Optical Circuit Switch (OCS) brings a new level of scalability, latency, and power efficiency to cloud‑scale and AI/ML data center networks. Built on field‑proven Lumentum micro‑electro‑mechanical systems (MEMS) technology with over a trillion mirror operating hours, the R300 establishes direct optical paths between endpoints—eliminating intermediate packet processing and optical‑electrical‑optical (OEO) conversion. The result is dramatically lower latency, higher signal integrity, and significant reductions in network power for large GPU clusters.

Key Features

  • High‑radix 300×300 optical switching for dense, scalable interconnect fabrics in front‑end and back‑end data center networks
  • Ultra‑low latency direct optical paths—5–10× lower than packet‑switched alternatives
  • Power‑efficient architecture: eliminates repeated OEO conversions
  • Wideband operation across O and C bands for maximum wavelength plan flexibility and future‑proof upgrades
  • Protocol‑agnostic optical core supports Ethernet, InfiniBand, and proprietary links at any data rate within supported bands
  • Reliability at scale: proprietary MEMS control without closed‑loop dither, plus redundant fans and power supplies and hot‑swappable control electronics.
  • Operational simplicity: fully passive optical switching core; modular design simplifies service and minimizes downtime
  • Open integration with SDN/orchestration via standard management interfaces (e.g., gNMI) for dynamic path provisioning

Applications

  • AI/ML training and inference fabrics (east‑west heavy traffic)
  • Spine replacement and scale‑out/scale‑up GPU cluster interconnects
  • Front‑end and back‑end data center networks
  • Data center interconnect (DCI)
  • Optical transport/telecom environments seeking deterministic, low‑latency switching
