1M 4 Ports C+L 1520~1620nm Polarization Insensitive Optical Circulator

Fiber-Mart’s Four-port Optical Circulator is a special type of circulator that has one input (port 1), one output (port 4) and two common ports (port 2&3). The light goes through port 1 to port 2. At port 2, any incoming light is guided to port 3 as output, while all input from port 3 is guided to port 4 as output.
Compared to three-port circulator, four-port device has one additional bi-directional port. Hence, it can be used to construct more flexible or more complex optical fiber sub-systems, such as add/drop module, mux/demux module, multi-port bi-directional splitters, WDM optical router, etc.

Characteristics

  • Low Back Reflection
  • High Extinction Ratio
  • Low Insertion Loss
  • High Return Loss

Applications

  • DWDM system
  • Add-Drop Multiplexing
  • Fiber Amplifier
  • Fiber Sensor
  • Chromatic Dispersion Compensation Devices
  • Fiber Bragg Grating
  • Polarization maintaining optical system

Application Diagram

Below are Three Port Circulator application for your reference.

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. The remaining signals pass through the FBG and exit on the top fiber.
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. See the example to the left.
Circulator can be used to send optical signals through a single fiber in two directions.
