Fiber Optic Cable Tie Installation
Fiber is fragile: The right cable tie prevents crushing and signal degradation. Use gentler options: Hook-and-loop, low-tension, and releasable ties protect fibers. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. During installation, all curvatures should be smooth. On long runs, use proper lubricants and make sure they are compatible with the cable jacket. Standards matter: Follow TIA-568, BICSI, NFPA 70, and UL requirements. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables can be installed in raceways, cable trays above ceilings or under. The SPEEDWRAP ® Brand FIBERtie™ product line includes cut-to-length tapes and fabricated cable ties. The self-gripping fastener's unique design enables the installer to quickly wrap the tie around a bundle of.
