Circulator

SENKO’s Mini Fiber Optical Circulator features a compact size and high performance over wide wavelength band. The component can transmit the incoming signal from port1 to port2, and another incoming signal from port2 to port3. It’s widely used in combination with fiber gratings and other reflective components in DWDM and bi-directional communication systems.

A fiber optic circulator is three-port devise that is designed to take the signal and route it to the adjacent channel. When the light enters port 1, it is routed to port 2. When the light enters port 2, it is routed to port 3. When the light enters port 3, it is routed to port 1. Its main function is to separate optical signals that are traveling in opposing directions.

 

Circulators can often be found in networks where bi-directional transmission is needed. Due to the high isolations and low insertion loss of the optical circulator, it is a great choice in advanced communication systems.
