The 4-Port 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. This PM Optical Circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.

1IL is 0.5 dB higher, RL is 5 dB lower, and ER is 2 dB lower for each connector added. Connector key is aligned to slow axis.
2The routing path: Type A: 1 - > 2, 2 - > 3, 3 - > 4; Type B: 1 - > 2, 2 - > 3, 3 - > 4, 4 - > 1.
3The optical path is aligned to slow axis while fast axis is blocked.
