Description of 3 Port Optical Circulator
| 3 Ports Optical Circulator Fiber Optical Circulator 1550nm LC UPC Connector ABS Box 3 port Optical Circulator GEZHI optical circulator is a special optical passive component that can be used to separate optical powers that travel in opposite directions in one single optical fiber, analogous to the operation of an electronic circulator. An optical circulator is a three-port device that allows light to travel in only one direction - from port 1 to port 2, then from port 2 to port 3. This feature is very important to optical bidirectional transmission and communication. Usually, it was use for optical transceiver, FBG filter and optical amplifier. |

Application Diagram of 3 Port Optical Circulator
As the picture shows: The input DWDM channels are coupled into Port 1 of the device with a FBG device connected to Port 2. The single wavelength reflected from the FBG then reenters the Circulator in Port 2 and is routed accordingly to Port 3.
Circulator used to drop an optical channel from a DWDM system using a Fiber Bragg Grating.
As the picture shows: 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.
Circulator can be used to send optical signals through a single fiber in two directions.
