Fused Biconical Taper (FBT) Optical Splitter Series

Fused Biconical Taper (FBT) optical splitter is made by bundling two or more optical fibers, then fusing and stretching them on a tapering machine, and real-time monitoring the change of splitting ratio. When the splitting ratio meets the requirements, the fusion and stretching are ended. One end retains one optical fiber (the rest are cut off) as the input end, and the other end serves as multiple output ends.
