Description
The Polarization Maintaining (PM) Filter Coupler (fast axis blocked) 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 various ratios. The PM Filter Coupler supports the light wave of each polarization to work, without blocking any polarization. So, it performs properly in FOCT, GYRO, and other polarization maintaining fiber system. It is widely used in fiber optic system monitoring and WDM system testing application.
