A fiber optic fusion splicer is a device that uses an electric arc to melt two optical fibers together at their end faces, to form a single long fiber. The resulting joint, or fusion splice, permanently joins the two glass fibers end to end, so that optical light signals can pass from one fiber into the other with very little loss.
The process of fusion splicing may vary, depending on the type of fusion splicer used. Fusion splicing permanently joins two optical fibers when no additional changes to those fibers are expected at that juncture. This is in contrast to connectors, which are designed to allow quick re-configuration of fiber links. Before optical fibers can be successfully fusion-spliced, they need to be carefully stripped of their outer jackets and polymer coating, thoroughly cleaned, and then precisely cleaved to form smooth, perpendicular end faces. Once all of this has been completed, each fiber is placed into a holder in the splicer’s enclosure.
Ensure the fiber ends are properly stripped, cleaned, cleaved and protected, a number of tools must be used to maintain the quality and integrity of the optical fiber splice, such as fiber optic cleaver, fusion splicer. Fiber optic cleaver is used to cut the fiberglass to make a good end face, as we know the quality of the bare fiber end face will determine the quality of the joint of the fibers in the fiber optic fusion process, and the joint point quality means higher or lower attenuation of the fiber connection line. So the fiber optic cleaver is very important in the fiber splicing process, it works together with the fusion splicer to meet the end needs. Fusion splicing uses an electric arc to weld the two optical fiber ends together and create a splice which has a very low insertion loss (<0.1dB). However, the splices themselves are very inexpensive when created by a fusion splicer. Mechanical splices, not requiring a fusion splicer machine, are very expensive on a per-splice basis. The fusion splicer machine is a very complex machine which, in some cases, is fully automatic. It preps, cleaves, then fuses the fibers.
