During hardware installation, cut the corrugated pipe to the desired length and wrap adhesive tape around the sharp ends to protect the optical fiber. Do not forcibly pull or excessively bend optical fibers during routing. There should be no other cables on the optical. While fusion splicing is the primary method for permanently joining two fiber ends for signal continuity, adhesives play a crucial role in various other aspects of fiber optic cable assembly and component manufacturing. This document describes the specifications for preparing, routing, and bundling cables and attaching labels to these cables. Adhesives for fiber optic components that perform well on glass, metal, ceramic and most plastic substrates provide excellent chemical and solvent. Most industry-specific tools are quite expensive, but common fiber optic technician actions when installing connectors and splices can be performed safely and cleanly using inexpensive duct, cellophane and painter's tape. One potentially hazardous aspect of fiber optic connector and splice. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed.
