4 Port Polarization Insensitive Optical Circulator


The 4 port polarization insensitive optical circulator is a compact high performance lightwave component that transmits the incoming signal from port 1 to port 2, the 2nd signal from port 2 to port 3 and the 3rd signal from port 3 to port 4. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
