Learn how to splice fiber optic cable using fusion splicing with this complete step-by-step guide. 652), cost analysis, and FAQs for network engineers and installers. Static electricity is an enemy of fiber optics and splicer electronics, especially in dry environments and/or air conditioning. 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. Steps to use this equipment and including how to test your fiber splice. 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. 15 dB, with well-executed splices often achieving losses below 0.
