optical splitterThe function is to divide the backbone optical cable into several parts through a splitter and connect them to the road equipment through optical fibers for transmission to the user unit. They complement each other.

optical splitterAlso known as a splitter, it is one of the important passive components in fiber optic links, which is a fiber optic junction device with multiple input and output ends.

optical splitterAccording to the principle of light splitting, it can be divided into two types: fused tapered and planar waveguide. The fused tapered method is to perturb two (or more) optical fibers without coating layer in a certain way, melt them under high temperature heating, and stretch them to both sides, finally forming a special waveguide structure in the form of a double cone in the heating zone. By controlling the angle of fiber twisting and the length of stretching, different light splitting ratios can be obtained. Finally, the tapered area is cured with adhesive on a quartz substrate and inserted into a stainless steel tube, which is the optical splitter. This production process is prone to damage to the optical splitter due to the inconsistency between the thermal expansion coefficient of the cured adhesive and that of quartz substrates and stainless steel pipes, resulting in varying degrees of thermal expansion and contraction when the ambient temperature changes. This is especially true when the optical splitter is placed outdoors, which is the main reason why it is prone to damage. For the production of more splitters, multiple splitters can be used.
