As AI models grow, so does the pressure on data center interconnects.
OCS (Optical Circuit Switching) is emerging as a key enabler—allowing physical-layer switching directly in the optical domain. It tackles two major challenges:
✅ Replacing traditional packet switching → lower power, lower latency, and breaking electrical bandwidth limits
✅ Enabling all-optical or co-packaged interconnects → dynamic, efficient physical networks for GPU clusters
But here's what's often overlooked: the optical circulator plays a critical role inside OCS systems.
It enables single-fiber bidirectional transmission, effectively doubling port density without adding more fibers. It also simplifies optical paths and reduces crosstalk.
At ORTE Photonics (24 years in optical comms), we've designed our circulators specifically for OCS and other high-isolation, low-loss applications:
🔹 0.8dB typical insertion loss – minimizing power budget loss
🔹 40dB isolation – suppressing crosstalk, protecting SNR
🔹 20K units/month stable delivery – reliable, cost-effective, and scalable
As data centers move toward 800G/1.6T and better energy efficiency, a solid optical foundation starts with the right components.
