Overview

Product details

Overview

The FT-1040-4 stops reverse-traveling light in 1040 nm fiber chains that do not preserve polarization. Two continuous-wave power classes are available, 10 W and 20 W, with extra headroom for nanosecond pulses. Forward transmission keeps insertion loss low and polarization dependence small while the reverse direction is strongly attenuated. Typical installation points include fiber laser outputs, testing instruments and fiber sensor interrogation units. Reverse isolation protects pump diodes and seed lasers from destabilizing feedback, and the non-PM design fits systems that do not maintain polarization. Package dimensions, tensile limits and operating temperatures are given in the specification table.
