2050nm 1×3/3×3 Single-mode Optical Fiber Tapered Coupler SM Fiber Optic Coupler

The fused tapered 1X3/3×3 one-time molded single-mode optical fiber tapered coupler (FBT Coupler) produced by TaorLab can couple the optical signal transmitted in the optical fiber in the coupling area of the special structure to redistribute the optical power. We produce couplers with various wavelengths and different splitting ratios in the range of 400-2050nm. Fused tapered splitters are widely used in optical fiber communications, underwater laser communications, fiber lasers, fiber amplifiers and other fields.
