High ER Polarization-Maintaining Filter Coupler 1310 nm–1550 nm, 500 mW
The High ER Polarization Maintaining Filter Coupler is a high-performance PM fiber filter coupler designed for 1310nm–1550nm wide-band operation. It features an ultra-high extinction ratio (≥25dB),), low insertion loss, high return loss, and supports 500mW CW power handling. Built with a PM Panda fiber design to ensure stable polarization state transmission, it is available in 1×2 and 2×2 port configurations with multiple splitting ratio options. Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards and RoHS certified. Widely used in ultrafast laser systems, fiber amplifiers, fiber sensing, communication systems, test instruments, and polarization-maintaining optical systems.
