    • 1×2/2×2 single-window broadband fiber optic coupler at 780

    The 780nm fused-taper single-window broadband fiber coupler (also called FBT Coupler) produced by Idealphotonics can couple the optical signal transmitted in the optical fiber in the coupling area of ​​the special structure to redistribute the optical power. It can be monitored in real time as needed and can produce unequal splitters in single-window, double-window and triple-window forms. Fused-taper splitters are widely used in fiber lasers, communication systems and OCT systems.

    产品特点Low additional loss、 Multiple coupling ratios、 Compact size、 High stability and reliability
