(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.
l Different combinations of coupling ratio.
l Low crosstalk & excess loss.
l High optical return loss.
l Available in dual/single wavelength operation.
l Optional connectors termination upon request.
