Low Insertion Loss FBT Fiber Otic Splitter for FTTH and CATV
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, FBT splitter is more affordable.
