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.

The PM Dense Wavelength Division Multiplexer is manufactured toTelcordia standard, based on environmentally stable thin film filter technology.  The PM DWDM is designed mainly for signals adding/dropping on OADM, and Mux/Demux DWDM commucation system,with the advantage of high isolation, high extinction ration, low insertion loss, excellent environmental stability, and high power handling capability

the PM Filter Coupler( both axis working) is characterized with low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability, widely applied as a PM splitter,which can divide the signal into variousratios.the PM Filter Coupler support the lightwave of  each polarization to work, without blocking any polarization. So, It performs prosperly in Foct,Gyro,and other polarization maintaining fiber system
