Technical Field

[0002] Fiber fusion splicers generally work on optical fibers and optical cables. Generally, they generate high-voltage arcs through electrodes to merge two optical fibers into one for use, so they are also called optical cable fusion splicers. The main function of fusion splicers is to facilitate the maintenance and emergency repair of optical fiber cable lines. Since it is difficult to fuse optical fibers with the naked eye, the operation of fiber fusion splicers is very dependent on the lens inside the fiber fusion splicer. Through the lens, the fiber fusion process and the fusion effect can be observed more intuitively and clearly. However, during the use of existing fiber fusion splicers,
[0003] The combined connection of optical fibers is often performed by fusion splicing using an optical fiber fusion splicer. The alignment device used in a conventional optical fiber fusion splicer is a folding clamping structure, which can easily cause the optical fiber to shift after clamping. This makes it difficult to maintain axial alignment during the optical fiber fusion splicing process, resulting in nodules after fusion splicing, affecting the connection effect.
