Fiber Optical Accessories FTTH Passive Optical Device FBT Optial Fiber Splitter Coupler
(FBT) Fused Biconical Taper splitter based on the traditional technology, it is to bundle together two or more optical fibers, and then pull the cone machine melt stretching, and real-time monitoring the change of the ratio, spectral ratio requirements after melt stretching, one side retain a single fiber (the rest of the cut) as input, the other end is a multi-channel output
