According to the principle, optical splitters can be divided into fused tapered type and planar waveguide type [1]. Two types, the fused tapered type product is made by side-welding two or more optical fibers; the planar waveguide type is a micro-optical component type product that uses photolithography technology to form an optical waveguide on a medium or semiconductor substrate to achieve branch distribution. Function. The two types of light splitting principles are similar. They achieve different branch sizes by changing the evanescent field coupling between optical fibers (coupling degree, coupling length) and changing the fiber radius. Conversely, multiple optical signals can be combined into one signal. It's called a synthesizer. Fused cone fiber optic couplers have become the mainstream manufacturing technology in the market due to their simple manufacturing method, low price, easy connection with external optical fibers and the ability to withstand mechanical vibration and temperature changes.

It means that two (or more) optical fibers with the coating layer removed are disturbed in a certain way, melted under high-temperature heating, and stretched to both sides at the same time, and finally form a special waveguide structure in the form of a double cone in the heating zone. By controlling the twisting angle and stretching length of the optical fiber, different light splitting ratios can be obtained. Finally, the tapered area is solidified on the quartz substrate with curing glue and inserted into the stainless copper tube. This is the optical splitter. This production process is inconsistent with the thermal expansion coefficient of the cured glue and the quartz substrate and stainless steel tube. When the ambient temperature changes, the degree of thermal expansion and contraction is inconsistent. This situation can easily lead to damage to the optical splitter, especially the optical splitter. The situation is even worse when placed in the wild, which is also the main reason why optical splitters are easily damaged. For the production of splitters with more channels, multiple splitters can be used.
Fused Fiber Splitter is used to transmit and distribute signals. Fused Fiber Splitter technology is to bundle two or more optical fibers together, then fuse and stretch them on a tapering machine, and monitor the changes in the splitting ratio in real time. After the ratio reaches the required ratio, the melting and drawing is completed. One end of the optical fiber is retained (the rest is cut off) as the input end, and the other end is used as a multi-channel output end. The mature tapering process can only draw less than 1×4 at a time. For devices above 1×4, use multiple 1×2 to connect them together. Then the whole package is packaged in the splitter box. [2]
