4 Port PM Circulator, Pigtailed (Path: 1→2, 2→3, 3→4)

The 2x2 Polarization Maintaining Optical Circulator is a compact, high performance light-wave component that can be used to separate signals traveling in opposite directions along fibers by transmitting signals from port 1 to port 2, from port 2 to port 3, and from port 3 to port 4. This component provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability. It can be used in any application for which directional isolation and constant state of polarization are important, including fiber lasers, fiber sensors, and bi-directional fiber communication systems.
