the Polarization Maintaining 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.

the Polarization Maintaining Optical Circulator (both axis working) 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. It supports the lightwave of  each polarization to work, without blocking any polarization, The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.

the PM Isolator is disigned to transmit positive light ,while blocking the reflected light from the terminal. The PM isolator is characterized with low insertion loss, high isolation, high return loss, high extinction ratio and excellent environmental stability and reliability. it´s the critical device of polarization maintaining fiber amplifers, fiber lasers, high speed communication systems and instrumentation applications, EDFA, PM Isolator has ´slow axis working,fast axis blocked´ and ´both axis woring´ can be selected
