2 μm 4-Port Polarization Maintaining Circulator

The 2 × 2 Polarization Maintaining Optical Circulator is a compact, high performance 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. The optical circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
