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.
