2000nm 1×2/2×2 Single Mode Optical Fiber Tapered Coupler SM Fiber Coupler
The fused tapered 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 with a special structure and redistribute the optical power. It can produce a range of 400-2050nm. Couplers of various wavelengths and different splitting ratios, and fused tapered splitters are widely used in optical fiber communications, underwater laser communications, fiber lasers, fiber amplifiers and other fields.
