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

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.

Product features：Low additional loss、 Multiple coupling ratios、 Compact size、 High stability and reliability

Part Number：--

Application area：Fiber laser、 Fiber sensor、 OCT medical field、 Optical communication field、 Fiber instrument inspection, etc
