Mass fusion splicers should be used for splicing ribbon fiber as they allow all 12 fibers to be fused simultaneously, significantly saving time and money. Clean Fiber Clean the fiber again with a lint free wipe. The most efficient way to terminate a fiber run is by using a pigtail. A fiber pigtail is a short length of optical fiber that comes with a high-quality, factory-polished connector already installed on one end, leaving a length of exposed glass on the other. Instead of building a connector from. Fiber optic fusion splicing is on the rise and Corning's Pigtailed Splice Cassettes enable faster field splicing and easy modular management of connectorization within the housing. Although the cost of a Fusion Splicer. Fusion Splicing means securely connecting two optical fiber cables by heating their core end faces and pushing them together to fuse them as a spliced single fiber that can transfer light signals with near zero loss at the splicing point.
