FBT Splitter

Description

Fused Biconical Taper is to tie together with two or more optical fibers, and then fused stretching in the biconical tapering machine , and monitoring the real-time change of splitting ratio, after splitting ratio meet requirements, fused stretching is overed, one side retain a single fiber (the rest is cuted) as input port, another side is regarded as multi-channel output port.

In some applications that are not very sensitive to volume and light wavelength, especially in the case of one minute two (less branching), FBT splitter is more affordable.
