p>The Fiber Optic Circulators are non-reciprocal advanced passive devices that direct light sequentially from port 1 to port 2, port 2 to port 3 and so on in only one direction. Unlike Fiber Optic Isolators, Fiber Optic Circulators do not disregard backward propagating light from the input fiber, but rather route it to another port. Circulators are used in Bi-Directional and High-Speed Communication Systems, DWDM Networks, Fiber Amplifiers, Fiber Sensors, OTDR Measurements.
