  • What is the fusion method for multimode optical fiber

    What is the fusion method for multimode optical fiber

    Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. 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. Regardless of your level of experience, creating high-quality, high-performance fiber optic networks requires developing your skills in fusion splicing. It details the crucial requirements for achieving high-quality splices with losses as low as 0.
