the PM Filter Coupler(fast axis blocked) performces as both in-line polarizer and the PM Coupler in a compact component,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 transmitt light of specific polarizaion, blocking the others. So, It performce prosperly in Foct,Gyro,and other polarization maintaining fiber system
