1×2 fbt sm splitter different splitting ratio(splitting ratio 50:50)

Fused  Biconic Taper  (FBT splitter) bundles two or more fibers together, and then melts and stretches them on a taper, and monitors the change of the split ratio in real time. After the split ratio reaches the requirement, the melt stretch is completed, and one end of the fiber is retained. (The rest is cut off) as the input, and the other end is used as the multi-output.
