PM Isolator 850nm 

Description 

The Polarization Maintaining Isolator (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
