What Is Fusion Splicer?

Fusion splicer may be the act of joining two optical fibers end-to-end using heat. The thing is to fuse both the fibers together in such a way that light passing with the fibers is not scattered or reflected back from the splice, and thus the splice as well as the region surrounding it are almost as strong because virgin fiber itself. The basic fusion splicer apparatus includes two fixtures which the fibers are mounted and two electrodes. Inspection microscope assists in the placement in the prepared fiber ends into a fusion-splicing apparatus. The fibers they fit in to the apparatus, aligned, and then fused together.

Initially, fusion splicing used nichrome wire as the heating unit to melt or fuse fibers together. New fusion-splicing techniques have replaced the nichrome wire with fractional co2 lasers, electric arcs, or gas flames to heat the fiber ends, causing them to fuse together. The little size of the fusion splice along with the development of automated fusion-splicing machines make electric arc fusion the most popular splicing approaches to commercial applications.
