1X2 1550nm Polarization Maintaining Optical Circulator
FiberZON's Polarization-Maintaining (PM) Optic Circulators are non-reciprocating, unidirectional, three-port devices that are used in a wide range of optical setups. Available with a center wavelength of 1064, 1310 (O-Band), or 1550nm (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.

Application Diagram
Circulator used to drop an optical channel from a DWDM system using a Fiber Bragg Grating.
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 can be used to send optical signals through a single fiber in two directions.
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.
