1550nm 1×2/2×2 Polarization Maintaining Optical Fiber Tapered Coupler

The fused tapered single-mode polarization-maintaining fiber tapered coupler (PM FBT Coupler) produced by TaorLab can couple the optical signal transmitted in the optical fiber in the coupling area of the special structure and redistribute the optical power. It can produce 400- Couplers with various wavelengths and different splitting ratios within the 2050nm range, and fused tapered splitters are widely used in optical fiber communications, underwater laser communications, fiber lasers, fiber amplifiers and other fields.
