An optical circulator is a device that routes light in a specific direction in an optical fiber. It is a three-port device that operates on the principle of nonreciprocity, meaning that light travels in a particular direction and does not return to its source.

The example below depicts the use of a circulator to drop an optical channel from a DWDM system using a Fiber Bragg Grating (FBG). The input DWDM channels are coupled into Port 1 of the device with an FBG device connected to Port 2. The single wavelength reflected from the FBG reenters the circulator in port 2 and is routed to Port 3. The remaining signals pass through the FBG and exit on the top fiber.

Circulators can also be used to send an optical signal in two directions down a single fiber. A circulator is located at both ends of the fiber. Each circulator functions to add a signal in one direction while removing the signal in the other. See the example below.
