3 Ports C+L (1520~1620)nm Polarization Insensitive Optical Circulator

Optical Circulator 3 Ports C+L (1520~1620nm) Polarization Insensitive C Band L Band Fiber Optical Circulator 1M Pigtailed

Fiber-Mart’s Three-port Optical Circulator allows light to travel in only one direction. A signal entering to Port 1 will exit Port 2 with minimal loss, while a signal entering Port 2 will exit Port 3 with minimal loss. Light entering port 2 experiences a large amount of loss at port 1, and light entering port 3 experiences a large amount of loss at ports 2 and 1. C band Optical circulators are non-reciprocal devices. This means that any changes in the properties of the light caused by passing through the device are not reversed by traveling in the opposite direction.

L Band Optical Circulator is widely used in advanced communication systems and fiber-optical sensor systems.
All Fiber-Mart's products are qualification tested.

Application Diagram

	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.
