Polarization Maintaining Filter Coupler(both axis working)

0.0/5 rating (0 votes)

Description

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
