Fused biconical taper( FBT)
1X2-64, FBT optical splitter is to bundle two or more optical fibers together, and then melt and draw on the taper machine, and monitor the change of the splitting ratio in real time. After the splitting ratio reaches the requirements, the melt-drawing is ended. One end of the fiber is reserved (cut the rest) as the input , and the other end is used as the multi-outputs.
