The fused biconical (FBT) optical splitter uses the traditional fused biconical process to disturb two (or more) coated optical fibers in a certain way, melt under high temperature heating, stretch to both sides at the same time, and finally form a special waveguide structure in the form of double cone in the heating zone. By controlling the torsion angle and stretching length of the optical fiber, Different spectral ratios can be obtained.
Fused biconical taper (FBT) optical splitter has more than 20 years of history and experience, and its production process has been very mature. Because its raw materials are quartz substrate, optical fiber, heat shrinkable tube and stainless steel tube, it is widely used in various passive optical networks, especially in applications with small shunt scale (such as 1:2, 1:4, etc.)
