2X2 1310nm Polarization Maintaining Optical Circulator 1M

Fiber-Mart’s 2x2 Polarization-Maintaining (PM) Optic Circulators is a compact, high performance light-wave component that can be used to separate signals. Traveling in opposite directions along fibers by transmitting signals from port 1 to port 2, from port 2 to port 3, and from port 3 to port 4. This component provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
The route path is the traditional routing from port 1 to port 4.
Choose from versions with no connectors, FC/ST/SC/LC PC&APC connectors and so on.

Characteristics

Low Back Reflection
High Extinction Ratio
Low Insertion Loss
High Return Loss
Excellent environmental stability and reliability

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.
Circulator can be used to send optical signals through a single fiber in two directions.
