How an Optical Circulator Works in a Fiber Network
By placing a circulator at each end of a fiber link, one port is used for transmission and the adjacent port for reception, allowing two
An optical circulator is a passive, non-reciprocal, multi-port device typically designed with three or four terminals. It ensures that light entering any port is transferred sequentially to the next adjacent port in a specific, predetermined direction. Typically, a circulator has three or four optical ports (inputs / outputs). Thorlabs' Optical Circulators are non-reciprocating, one-directional, three port devices which are great for bidirectional propagation of light in a single fiber. Its primary function is to enable bi-directional signal transmission.
