64x64 Optical Circuit Switch (OCS)

R64

OCS64

The Lumentum R64 Optical Circuit Switch (OCS) brings deterministic, low‑latency, and power‑efficient optical connectivity to AI/ML and cloud‑scale data centers. Built on Lumentum’s field‑proven micro‑electro‑mechanical systems (MEMS) technology—deployed across telecom networks with more than a trillion mirror operating hours—the R64 establishes direct any‑to‑any optical paths while maintaining exceptional signal integrity. Its compact 2RU platform is architected for modern data centers with modular serviceability and open software integration.

Key Features

  • 64×64 radix ideal for GPU interconnect fabrics and data center interconnect (DCI) applications
  • Compact 2RU system with easy‑mount rails, modular/redundant PSUs and fans
  • SONiC‑based OS with gNMI connection management for SDN/orchestrator integration
  • Ultra‑low insertion loss: typically < 1.2 dB in O‑band
  • Wideband operation: O + C bands
  • Protocol/data‑rate agnostic: use any data rate or modulation format—today or tomorrow
  • Field‑proven, ultra‑stable MEMS technology with no dither feedback required
  • Low‑power architecture enabling significant network‑level power savings versus packet‑switched alternatives

Applications

  • AI/ML cluster fabric (east‑west traffic)
  • GPU interconnect scale‑out/scale‑up
  • Data center interconnect (DCI)
