NEW CASTLE, DE — FS has launched the DCS-W Series All-Optical Circuit Switch (OCS), a new product line developed in-house to address the growing demands of artificial intelligence, high-performance computing (HPC), and machine learning clusters.
Unlike conventional optical-electrical-optical (OEO) devices, the DCS-W Series relies on an all-optical design that eliminates signal conversion. The result is protocol- and rate-transparent transmission with ultra-low latency, higher energy efficiency, and scalability suited to modern data-intensive workloads. Available in 8×8, 16×16, and 32×32 matrix configurations, the switch is designed for environments ranging from research labs to large-scale GPU interconnects and AI training clusters.
The architecture supports true any-to-any port connections, providing congestion-free communication and smooth traffic management in complex and dynamic topologies. The platform accommodates a wide range of data rates — from 1G up to 800G, with future compatibility for 1.6T — and works seamlessly with Ethernet, OTN, SDH, Fibre Channel, and other major protocols. This broad compatibility allows organizations to scale without costly upgrades or protocol-specific adaptations.
To enhance reliability, the switch incorporates built-in Optical Power Detection (OPD) that continuously monitors signal strength at each port, enabling faster detection of issues such as attenuation or fiber breaks. For operations teams, an intuitive browser-based interface delivers real-time status updates and alarm notifications, reducing reliance on complex command-line interfaces and simplifying deployment and troubleshooting.
“The DCS-W Series reflects FS’s commitment to intelligent, reconfigurable optical networks,” said Bener Peng, product R&D manager at FS. “It enables programmable, flexible topologies for data centers and AI/HPC clusters, while reducing power, cost, hardware complexity, and latency, and improving overall network availability.”
The DCS-W Series launches as a single-mode MEMS-based OCS, with plans to expand into multimode and customizable options to address evolving market requirements. The release positions FS as a player in next-generation optical switching solutions at a time when AI-driven workloads are driving unprecedented demand for high-speed, low-latency networking.
