Product details
Overview
Built for 1080 nm fiber systems, the FT-1080-3 blocks backward-traveling light while running on ordinary non-PM fiber. Two continuous-wave power classes are offered, 10 W and 20 W, with additional headroom for nanosecond-pulse peaks. The forward direction keeps insertion loss low and polarization dependence small; the reverse direction is strongly attenuated. Common placement includes fiber laser outputs, test benches and sensor interrogation units. Stopping feedback into pump diodes and seed lasers keeps high-power sources stable over long operating runs, and the non-PM build fits standard fiber plants.
