Fusion Splicing is a preferred way to join two fibers together by using heat. Whether the fiber was broken or not long enough, a fusion splicer will make your job easier. Splicing fiber optic cable is a fairly simple procedure. Prepared fiber ends are placed in the splicer and automatically aligned and then fused together. This method ensures greater reliability with less light being scattered or reflected back by the splice and with the splice itself being as strong as the original optical fiber.
The process of fusion splicing normally involves heat to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion.
1, Stripping the fiber
Stripping is the act of removing the protective polymer coating around optical fiber in preparation for fusion splicing.
2, Cleaning the fiber
The customary means to clean bare fibers is with alcohol and wipes.
3, Cleaving the fiber
The fiber is then cleaved using the score-and-break method so that its end-face is perfectly flat and perpendicular to the axis of the fiber.
4, Splicing the fibers
Current fusion splicers are either core or cladding alignment. Using one of these methods the two cleaved fibers are automatically aligned by the fusion splicer in the x,y plane, then are fused together.
