The Mini size PM Fiber Circulator (Fast axis blocked) is a compact light-wave assembly that comes in two types. One type is 1x2 that routes input signals from Port 1 to Port 2 and input Port 2 signals to Port 3 while blocking reflected light; The other type si 2x2 that routes input signals from Port 1 to Port 2, input port 2 to port 3, and input port 3 to port 4, while blocking reflected light. The device has high isolation, low insertion loss, high extinction ratio and excellent environmental stability.

Fiber circulators are multiport passive devices based on Faraday rotation. They route light unidirectionally along specified paths and provide high reverse isolation to suppress reflected-signal interference, supporting signal purity in communications and sensing. Applications include bidirectional transmission over one fiber, fiber-laser cavity isolation, sensing-system interference suppression, and directional beam routing in quantum-information research. They provide stable, efficient paths that improve optoelectronic-system performance and reliability.
