4 Steps in Fiber Optic Fusion splicer

Posted on by FS.COM

Fiber Optic 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 (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 (arc fusion) the most popular splicing approaches to commercial applications.

Splicing fiber optic cable ends together is often a precise process with hardly any room for error. This is because the optical fiber ends must be gathered absolutely perfectly to be able to minimize potential optical loss or light leakage. Properly splicing the cable ends demands the usage of a high-tech tool called a fusion splicer. A fusion splicer perfectly mates the optical fiber ends by melting or fusing them to the other. Splicing fiber cables surpasses using connectors considering that the fusing process results in a superior connection that features a lower level of optical loss. Now,I will introducts 4 steps to fusion splicing.


Know that fusion splicing is essentially several optical fibers being permanently joined together by welding utilizing an an electric arc. The need for an exact cleaver is suggested should you desire less light loss and reflection problems. Understand that an excellent cleaver just for this precise work is nessary. If your poor spice is created, the fiber ends may well not melt together properly and problems can arise.


Prepare the fiber by stripping the coatings, jackets and tubes, ensuring only bare fiber is left showing. You will need to clean all of the fibers associated with a filling gel. A clean environment is imperative for a good connection.


Cutter the fiber. A great wire cutter is suggested to secure a successful splice. When fusing the fibers together, either align the fibers manually or automatic, determined by what type of fusion splicer you’ve got. When you’ve got a new proper alignment, a power arc can be used to melt the fibers together creating a permanent weld of these two fiber ends.


Protect the fiber with heat shrink sleeve, silicone get. This can maintain your optical fiber resistant to any outside elements it may encounter or future breakage.

Alternatives to fusion splicing include using fiber optic connectors or mechanical splices because both versions have higher insertion losses, lower reliability far better return losses than fusion splicing.
