FS introduced its independently developed DCS-W Series All-Optical Circuit Switch (OCS) to support AI, HPC, and machine learning clusters. The fully non-blocking optical matrix design eliminates OEO conversion, delivering protocol- and rate-transparent transmission with ultra-low latency, high energy efficiency, and scalability. Offered in 8×8, 16×16, and 32×32 configurations, the switches target deployments ranging from labs to large-scale GPU training fabrics and HPC workloads.
The DCS-W Series supports data rates from 1 G up to 800 G, with readiness for 1.6 Tbps. Compatibility spans Ethernet, OTN, SDH, Fibre Channel, and other major protocols, helping reduce long-term operational costs. Built-in Optical Power Detection (OPD) provides continuous monitoring of port signal strength to identify fiber degradation or breaks. A browser-based Web GUI replaces complex CLI commands for configuration and diagnostics, streamlining operations and reducing deployment times.
FS introduced the initial models as single-mode MEMS-based OCS and plans to expand the family with multimode and customizable options. The platform is positioned to enhance existing networks or enable new, streamlined topologies for next-generation data centers.

“The DCS-W Series reflects FS’s commitment to intelligent, reconfigurable optical networks. It enables programmable, flexible topologies for data centers and AI/HPC clusters, enhancing existing networks or building streamlined architectures, while reducing power, cost, hardware complexity, and latency, and improving overall network availability,” said Bener Peng, Product R&D Manager of FS.
Analysis: In July 2025, the Open Compute Project Foundation (OCP) launched a new Optical Circuit Switching (OCS) Subproject aimed at accelerating the adoption of photonic switching technologies in AI data centers. Co-led by iPronics and Lumentum, the subproject brings together industry players including Google, Microsoft, Coherent, Lumotive, nEye, Oriole Networks, and POLATIS (HUBER+SUHNER) to develop open, interoperable solutions for high-bandwidth, low-latency networking.
