Low Insertion Loss 3 Port Optical Circulator with High Channel Isolation and Compact Package
Low Back Reflection Optical Circulator 3 Ports Fiber Module With FC Connector
Product Description
Gezhi's Optical circulators have many applications in optical circuits and optical communication systems for redirecting bidirectional optical signals into different ports.
An optical circulator is a special fiber-optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber, analogous to the operation of an electronic circulator. An optical circulator is a three-port device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1, but instead exits from port 3.

Application Diagram
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.
