Method for splicing armored fiber optic patch cords
Fusion splicing is most widely used as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint. Virtually all singlemode splices are fusion. Get the wrong connector type, the wrong polish, or skip proper fusion splicing technique—and you're looking at elevated signal loss, increased back reflection, and a. Generally, splices are used to connect two fibers permanently. Fusion splicing uses a machine to “weld” fibers together in an electric arc. Mechanical fibers clamp two fibers into alignment with index matching gel between them to. bers to be terminated from cable to cable or from cable to pigtail assemblies. What is Fiber Optic Splicing and Why is it Needed? – #1. This technique ensures high-performance data transmission and is essential in extending cable runs, repairing broken links, or establishing new network paths in data. As networks move to higher speeds and higher density, choosing the right fiber optic patch cords becomes critical to the reliability of your system.
