Wecome to the page of Reachoptics Polarization Maintaing Isolator, we also called PM Isolator. Reachoptics' PM Isolator is disigned to transmit positive light ,while blocking the reflected light from the terminal.Reachoptics could offer PM Isolator with operating wavelength 1310nm, 1480nm, 1550nm, L Band and 1064nm. Reachoptics' 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.
