1X2 1550nm 5W High Power Polarization Maintaining Optical Circulator, both fast and slow axis working, Single Stage/Dual Stage 900um
Fiber-Mart’sPolarization-Maintaining (PM) Optical Circulators are non-reciprocating, unidirectional, three-port devices that are used in a wide range of optical setups. Polarization Maintaining Circulator Available with a center wavelength of 1064, 1310 (O-Band), or 1550 nm (C-Band), these circulators are designed to work with light that is launched into the slow axis.
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. See the example to the left.
Circulator can be used to send optical signals through a single fiber in two directions.
