AI training clusters, GPU interconnects, and HPC workloads are straining traditional networking gear, and FS thinks it has the answer: cut out the conversion. The company today announced its DCS-W Series All-Optical Circuit Switch (OCS), an independently developed platform built to handle the bandwidth, latency, and energy demands of next-generation compute clusters.
Unlike traditional OEO (optical-electrical-optical) switches, which convert signals before transmission, FS’s all-optical design keeps data in its native light form. The result: protocol- and rate-transparent transmission, ultra-low latency, and higher efficiency.
Why It Matters
Networking infrastructure hasn’t always kept up with the pace of AI and HPC hardware. GPUs and specialized accelerators are scaling at breakneck speed, but data center interconnects often become bottlenecks. By going fully optical, FS aims to provide a future-proof backbone capable of supporting today’s 800G links and tomorrow’s 1.6T rates without costly upgrades.
The Specs: From Labs to Mega Clusters
The DCS-W Series comes in 8×8, 16×16, and 32×32 matrix sizes, making it flexible enough for everything from research environments to large-scale AI clusters. Key features include:
- All-optical, non-blocking architecture – Any-to-any port connectivity for congestion-free topologies.
- Protocol transparency – Supports Ethernet, OTN, SDH, Fibre Channel, and more.
- Built-in Optical Power Detection (OPD) – Real-time monitoring to quickly flag fiber breaks or signal loss.
- Web GUI management – A browser-based interface for monitoring, configuration, and troubleshooting without diving into command-line tools.
In short, FS isn’t just shipping a faster switch—it’s pitching programmable and intelligent optical control as a foundation for AI-native data centers.
Market Context: Joining the Race for Optical AI Fabrics
FS isn’t the only vendor eyeing AI-driven data centers. Companies like Arista, Cisco, and Infinera are also betting big on optical switching and photonic interconnects. What sets FS apart is its emphasis on simplicity and accessibility: no protocol-specific adaptation layers, no hidden lock-in, and a GUI that’s friendlier than most enterprise-grade tools.
“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 cutting power, cost, and complexity.”
What’s Next
The first release is a single-mode MEMS-based OCS, but FS has already teased plans for multimode and customizable versions tailored to evolving data center designs. That flexibility could help FS carve out space in a market increasingly defined by AI workloads and the relentless demand for faster, more efficient interconnects.
For enterprises and research labs trying to keep GPUs fed with data, FS’s all-optical bet could prove to be more than just a speed boost—it might be the missing link in scaling tomorrow’s AI superclusters.
