![]() In addition to lower splicing loss at 0.1dB typical, advantages of fusion splicing include less back reflection. With proper training, a fiber splicing technician can routinely achieve less than 0.1dB insertion loss splicing for both single-mode and multimode fiber cables. Generate a small electric arc to melt the fibers and weld them together.The fusion splicer performs optical fiber fusion splicing in two steps. This produces a transparent, non-reflective and continuous connection between the fibers enabling very low loss light transmission. In the fusion splicing process, a specialized fusion splicer machine is used to precisely align the two fiber ends then the glass ends are “fused” or “welded” together using an electric arc or some type of heat. The fusion method fuses the fiber cores together with less attenuation. ![]() Fusion Splicingįusion splicing is more expensive but has a longer life than mechanical splicing. They are available in permanent and reenterable types.įiber optic cable mechanical splices are available for single-mode or multimode fibers. But fiber mechanical splicing introduces higher reflection than the fusion splicing method.įiber optic cable mechanical splices are small, quite easy to use, and are very handy for either quick repairs or permanent installations. The fibers are not permanently joined, just precisely held together so that light can pass from one to another. This precisely aligns two bare fibers and then secures them mechanically.Ī snap-type cover, an adhesive cover, or both, are used to permanently fasten the splice. Mechanical splicing uses a small, mechanical splice, about 6cm long and 1cm in diameter that permanently joins the two optical fibers. Mechanical Splicingįiber optic cable mechanical splicing is an alternate splicing technique that does not require a fusion splicer.Ī mechanical splice is a junction of two or more optical fibers that are aligned and held in place by an assembly that holds the fiber in alignment using an index matching fluid. Both methods provide much lower insertion loss compared to fiber connectors. There are 2 methods of splicing, mechanical or fusion. Infield installations, splicing is a faster and more efficient method and is used to restore fiber optic cables when a buried cable is accidentally severed. ![]() Splicing is most commonly used in the field but has application in cable assembly houses. The other, more common, method of joining fibers is called termination or connectorization. To begin, the standard definition of splicing in optical fiber is joining two fiber optic cables together. We tend to receive the same basic questions on the topic of splicing on types, benefits and applications. Syringes, Tips, Pistons and Barrels, Plunger.
