What is fusion splice in fiber optic?
What is fusion splice in fiber optic?
Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers.
How do they splice fiber optic cable?
Mechanical splicing uses a small, mechanical splice, about 6cm long and 1cm in diameter that permanently joins the two optical fibers. This precisely aligns two bare fibers and then secures them mechanically. A snap-type cover, an adhesive cover, or both, are used to permanently fasten the splice.
How does a fusion splicer work?
Fusion splicing is to use high-temperature heat generated by electric arc and fuse two glass fibers together (end to end with fiber core aligned precisely). The tips of two fibers are butted together and heated so they melt together.
How long does it take to fusion splice fiber?
A single fusion splice may be something like $….2 x fiber techs or a fiber tech and assistant per joint.

What step should be performed at the beginning of every fusion splicing operation?
What step should be performed at the beginning of every fusion splicing operation? Make a number of test splices to set up the fusion splicer and to verify the instruments settings and calibration for both the environment and the type of fiber to be spliced.
How do you fuse fibers?
Fusing the fiber After the fibers have been cleaved, fuse them together with a fusion splicer. First, you must align the ends of the fiber within the splicer. Once properly aligned, melt the fibers with an electric arc, permanently welding the ends together.
How long does a fusion splice take?
What is the difference between fusion splicing and mechanical splicing?
Fusion splicing can be performed as a single fusion (fusing just one fiber at a time) or as a mass fusion (fusing 12 fibers in a single operation). Mechanical splicing doesn’t permanently join two fibers together; instead, it precisely “holds” them together, enabling light to pass from one fiber to the other.
What are some prerequisites before performing a fusion splice of optical fibers?
What are some prerequisites before performing a fusion splice of optical fibers? A controlled environment such as a splicing van, trailer, or tent and a stable work surface that is large enough to accommodate the fusion splicer, tools , and the splice closure.
How much does fusion splicing cost?
At $60-120/hr, a fusion splice in a drop location will cost $30-$60 labor plus the splicing cost. A mechanical splice would also require cable prep time, plus the $5 – $12 connector price.
