3 Port Polarization Maintaining Optical Circulator

 

Description 

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