3 Ports 1310/1550/1625nm Polarization Insensitive Optical Circulator, P Grade

A Polarization Insensitive Optical Circulator is a key optical communication device designed to direct light signals through multiple ports without being affected by the polarization state of the incoming signals. This feature ensures stable and efficient performance regardless of the polarization conditions, making it ideal for various applications. It typically has low insertion loss and high isolation, allowing for high-fidelity signal transmission with minimal interference. Widely used in fiber optic communication systems, such as WDM networks, optical sensing, and network testing, this circulator facilitates precise signal routing and measurement, enhancing overall system reliability and performance.

Application Diagram

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.
