INSTALLATION OF OPTICAL FIBER BACKBONE CABLES A. Comply with NECA 1, NECA 301 and NECA/BICSI 568. B. General Requirements for Optical Fiber Cabling Installation: 1. Comply with TIA-568-C.1 and TIA-568-C.3. 2.
Comply with BICSI ITSIMM, Ch. 6, "Cable Termination Practices." 3. Terminate all cables; no cable shall contain unterminated elements. Make terminations only at indicated outlets, terminals, cross-connects, and patch panels. 4. Cables may not be spliced. Secure and support cables at intervals not exceeding 30 inches (760 mm) and not more than 6 inches (150 mm) from cabinets, boxes, fittings, outlets, racks, frames, and terminals. 5. Install lacing bars to restrain cables, to prevent straining connections, and to prevent bending cables to smaller radii than minimums recommended by manufacturer. 6. Bundle, lace, and train cable to terminal points without exceeding manufacturer's limitations on bending radii, but not less than radii specified in BICSI ITSIMM, "Cabling Termination Practices" Chapter. Use lacing bars and distribution spools. 7. Do not install bruised, kinked, scored, deformed, or abraded cable. Do not splice cable between termination, tap, or junction points. Remove and discard cable if damaged during installation and replace it with new cable. 8. Cold-Weather Installation: Bring cable to room temperature before dereeling. Heat lamps shall not be used for heating. 9. In the communications equipment room, provide a 10-foot- (3-m-) long service loop on each end of cable. 10. Pulling Cable: Comply with BICSI ITSIMM, Ch. 4, "Pulling Cable." Monitor cable pull tensions. 11. Cable may be terminated on connecting hardware that is rack or cabinet mounted. C. Open-Cable Installation: 1. Install cabling with horizontal and vertical cable guides in telecommunications spaces with terminating hardware and interconnection equipment. 2. Cable shall not be run through structural members or in contact with pipes, ducts, or other potentially damaging items. D. Installation of Cable Routed Exposed under Raised Floors:
