Quick answer: Strip the fiber jacket and buffer, clean the bare glass with 99% IPA, cleave to under 1 degree, load both fibers into the splicer, run the splice cycle, heat-shrink the protection sleeve, and verify the splice loss. Total time per splice for an experienced tech is. This application note describes fundamental theory and applications behind optical fiber splicing for mechanical and, in particular, fusion spliced joints. Various fiber preparation, alignment, splicing and testing methods are discussed, as well as safety precautions and troubleshooting. The procedure is straightforward but unforgiving -- skip a step or get sloppy with prep, and the splice fails. This guide walks through the complete field. This Corning paper explains measurement behaviors of fusion spliced optical fibers and how glass properties and MFD (mode field diameter) differences across fiber splice junctions can lead to erroneous interpretations of splice loss when performing uni-directional OTDR (optical time domain. A fiber fusion splicer is one of the most important tools for deploying and maintaining FTTH networks, backbone fiber infrastructure, and data center cabling.
