Polarization Maintaining Optical Circulator 2X2 1310nm

2X2 1310nm Polarization Maintaining Optical Circulator 1M

Fiber-Online’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.
