Optical fiber splitter is a device used to realize the splitting and combining of light wave energy. It distributes the The optical splitter is the same as the coaxial cable transmission system. The optical network system also needs to couple, branch, and distribute the optical signal, which requires the optical splitter to achieve. Optical splitter, also known as optical splitter, is one of the most important passive devices in the optical fiber link. It is an optical fiber tandem device with multiple input ends and multiple output ends. M × N is commonly used to indicate that a splitter has M input terminals and N output terminals. The optical splitters used in the optical fiber CATV system are generally 1 × 2, 1 × 3 and the 1 × N optical splitter composed of them.
The optical splitter can be divided into a molten tapered type (FUSED FIBER SPLITTER / FBT SPLITTER) according to the splitting principle and planar waveguide type (PLC SPLITTER).

The principle of optical splitter
According to the principle, the optical splitter can be divided into two types: fused taper type and planar waveguide type. The fused taper type product is formed by fusing two or more optical fibers on the side; the planar waveguide type is a micro-optical element type product. The photolithography technology forms an optical waveguide on a dielectric or semiconductor substrate to realize the branch distribution function. The two types of beam splitting principles are similar. They change the coupling of the evanescent field between the optical fibers (coupling degree, coupling length) and the fiber radius to achieve branching of different sizes. Conversely, multiple optical signals can be combined into one signal. It's called a synthesizer. Fused cone optical fiber couplers are currently the mainstream manufacturing technology in the market because of their simple manufacturing methods, low prices, easy connection with external optical fibers, and the advantages of resistance to mechanical vibration and temperature changes.
The fusion taper method is to remove two (or more than two) optical fibers with a coating in a certain way, melt under high temperature heating, and simultaneously stretch to both sides, and eventually form a double cone in the heating zone The special waveguide structure can obtain different splitting ratios by controlling the twisting angle of the optical fiber and the length of stretching. Finally, the taper area is cured with a curing glue on the quartz substrate and inserted into the stainless copper tube, which is the optical splitter. In this production process, the thermal expansion coefficient of the cured adhesive is inconsistent with the quartz substrate and the stainless steel tube, and the degree of thermal expansion and contraction is inconsistent when the ambient temperature changes. This situation is likely to cause damage to the optical splitter, especially the optical splitter. The situation is even worse in the wild, which is also the main reason why the optical branch is easily damaged. For the production of more splitters, multiple splitters can be used.
