  • What is the principle of fusion splicing 36-core optical fiber cables

    What is the principle of fusion splicing 36-core optical fiber cables

    The principle of fusion splicing is a common method of making fiber splices. More precisely, the fiber ends are initially brought in close contact, with a small gap in between. This technique is used in optical fiber communication, in order to form long optical links for better as well as long-distance optical signal transmission. Splicers are basically couplers that form a connection. It is a technique that uses controlled heat to permanently fuse two optical fiber ends together. The goal is to fuse the two fibers together in such a way that light passing through the fibers is not scattered or reflected back by the splice, and so that the splice and the region surrounding it are almost as strong as the.
