Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. Static electricity is an enemy of fiber optics and splicer electronics, especially in dry environments and/or air conditioning. Unlike mechanical splicing, which relies on alignment sleeves and index-matching gel, this thermal approach creates a continuous glass path between fibers. Look at the slide graphics and then read the notes below. If you have your own equipment, do the recommended exercises. Therefore, we will also touch on cost factors, risk management, and best practices in. Fiber optic cable splicing becomes necessary when extending or repairing existing optical networks.
