Exploring the alignment connection method of optical fiber fusion splicer

The purpose of the fiber fusion splicer is mainly to achieve the connection of the fiber. Although there are many types of light fusion machines, the structure of the types of fiber fusion splicers is basically the same, that is, most of the optical fiber fusion splicers generally use high-precision components (two parts from two pins and one roller) Composition) to achieve an aligned connection of the fiber.
In this method, the fiber is inserted into and fixed in the pin, and the surface of the pin is polished to achieve alignment in the roll tube. The outer component of the pin is made of a metal or non-metal material, the butt end of the pin is honed, and the other end is usually supported by a bend limiting member to support the fiber or fiber soft a to relieve stress. The roller joint pipe is generally made of two semi-synthetic, fastened cylindrical members made of ceramic or beryllium copper, and is equipped with a metal or plastic flange to facilitate the installation and fixing of the fusion splicer. In order to align the fiber as much as possible, the processing precision of the pin and the roller is very high.
The optical fiber fusion splicer is mainly used in the construction and maintenance of optical cables in optical communication. Mainly by the discharge of the arc to melt the two fibers, while using the principle of collimation to gently push to achieve the coupling of the fiber mode field. It is also used in major telecom operators, engineering companies, private networks of enterprises and institutions, etc. It is also used for fiber fusion of optical fiber passive and active devices and modules.
