Polarization Maintaining Optical Circulator – 4 Port

Description 

The Polarization Maintaining Optical Circulator (PM Circulator) is a compact lightwave component that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3 and incoming Port 3 signals to Port 4, while blocking the reflected light. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
