Fused biconical taper is two (or more than two) removal of coated optical fiber to a certain method by the disturbance, under the high temperature heating melt, also to both sides of the stretch, eventually in the heating zone formed the special waveguide structure of the double cone form, different splitting ratio obtained through control fiber torsion angle and stretch length. The tapered region for curing adhesive on the quartz substrate into the stainless steel tube, which is the optical splitter. This production process from glue solidifying heat expansion coefficient and quartz substrate, stainless steel tube is inconsistent, in when the ambient temperature change, thermal expansion and contraction degree is inconsistent, this situation easily lead to damage to the optical splitter, especially the optical branching in the field even more, which is an optical splitter easy to damage the main reason. For the splitter production more channels can be composed of a plurality of two splitters.
