Product details
Overview
Built for 1080 nm polarization-maintaining paths, the FT-1080-5 stops backward-traveling light from reaching sensitive upstream devices. The 10 W and 20 W continuous-wave power classes cover demanding fiber laser and amplifier builds, and nanosecond-pulse peaks are handled without damage. Extinction ratio stays stable in the forward direction while reverse isolation remains strong, preserving the polarization state that coherent and interferometric systems depend on. Low insertion loss and strong return loss keep the forward signal clean. Typical users include ultra-fast fiber laser platforms, optical test benches and PM-fiber sensor networks.
