Splices are “permanent” connections between two fibers. Typically, the reason for choosing one method over the other is economics. Fusion splicing is lower per connection; however, the initial investment is much higher. Mechanical splices are simply alignment devi. Fiber optic cable transmit information as light pulses, rather than the electrical impulses used by traditional wire cables. They may be used to convey voice, video and data. The fiber optic cables have a glass core covered with cladding, coatings, and, typically, Kevlar membranes to add strength. Finally, a protective outer coating seals the cable. It is the optical fibers in the fiber optic cables that carry the light, and allow information to be transmitted. These consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough r. Fusion splicing involves joining two optical fibers end-to-end using some source of heat. The end result is fusing the two fibers together so that light passing through the fibers is not scattered or reflected back by the splice, and so that the splice and the region surrounding it are almost as strong as the virgin fiber itself. 1.
