Fiber Optic Cable Splicing Operation and Splicer Requirements
In this guide, you will find a chronological description of the fusion splicing process, the principal technical standards, and answers to the real-life questions network engineers and procurement teams may have. Fiber optic strands are ultra-lightweight and about as thin as human hair, and yet, they have more than eight times the pulling tension of a copper wire. And because fiber optic cables carry light instead of electricity, they are not affected by changes in the temperature and can withstand extreme. Splicing fiber optic cable is an extremely important phase for making dependable, high-speed communication infrastructures. 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.
