23.1 General
- Installation practices are detailed in order sections of the Telecommunications Specification. This section pertains to Caltech specific concerns regarding cable plant installations. If there is a conflict or question regarding which method to apply, contact Caltech for clarification.
23.2 Specifics
- No cables shall be installed in a fashion that contravenes either the minimum installed or the minimum under-load bend radius of the cable.

Do not allow innerduct to rest on electrical or mechanical equipment. Do not tie innerduct to power or other foreign services. Support innerduct running in the vertical and horizontal direction in place at not more than 12" and 48" centers respectively.
- No cable is to be pulled through a conduit “L-bend” (condulets). In existing routes with L-bends, the cables are to be pulled to the L-Bend. The cable is then to be carefully pulled through the remainder of the conduit run with best effort to maintain minimum required bend radius. New paths installed with "L-bend" connectors will be rejected for use.
- Install all cables in complete runs from outlet or patch panel to patch panel. In line joints, splices, distribution points or other intermediate connections are not permitted unless specifically called out by this specification.
- At no point shall the communications cables be tied to power cables or other building services or their supports, or run in the same ducts, raceways, conduits or connection boxes as power cabling. Copper data cables must maintain the specified distance separation from electrical lines and conduits per Industry specification.
- Use plenum-rated tie wraps in plenum spaces. All tie wraps shall be secured in such a way that it can be rotated around the cable bundle, so as to assure no cables have been cinched too tight. Velcro tie wraps (Hook and Loop One Wrap) are to be used copper cables, plastic tie wrap may be used for inner duct, armored fiber and other applications as specified by Caltech.
- Reinstate all pull-wires in conduits and ducts after use to facilitate future addition of cables.
- Cables shall not be held so tightly with cable ties that the cable jackets are indented by the cable ties.
- Individually and properly ground all equipment cabinets, racks and ladder rack. Ground all metallic sheath communications cables entering the building per manufacturer specifications and NEC 770-33, 800-33, 800-40 and EIA/TIA-607 (or newest EIA/TIA code which supersedes these).
- Ensure that all waste materials are disposed of in a safe manner. Pay particular attention to waste materials produced during the termination of optical fiber cabling. Ensure that all used components and fiber cut-offs are collected in purpose-made containers and disposed of properly.
- Replace all moisture and fire barrier material in ducts, conduits and other penetrations disturbed during installation of communications cabling. Install barrier material in all fire-rated penetrations that have cabling running through them. The barrier material shall be installed so the final penetration has the same fire rating as the original wall/floor.
- Provide expansion plugs in all ducts/conduits entering the building. Seal all unused ducts/conduits with plugs that allow the pull-string to be tied off on the inside.
- Use purpose-built pulling grips during cable installation. Do not pull cables by attaching pull wires to cable jackets, elements or reinforcement. Use strain gauges or equivalent measures to ensure that the maximum tensile load rating of the cables is not exceeded during installation.
- External Cables shall be run in underground ducts. Ducts shall be proven to be clear prior to pulling of cables. Cable pulling tension shall not exceed manufacturers limits. The cable pulling tension shall be applied smoothly without jerks and at no time shall it exceed the manufacturers limits.
- The pulling equipment for pulling external cables shall be arranged either to indicate the pulling tension, which shall be continually monitored during a pull, or shall mechanically assure that the maximum permissible tension is not exceeded.
- The number of cables in each conduit shall be controlled to allow for future cable installation and to stay within the manufacturers maximum allowable cable pulling tension. Conduit fill ratios shall not exceed the current requirements of the NEC.
- The maximum run length of each distribution cable shall not exceed the 85m limit specified by EIA/TIA 568A. Notify Caltech immediately if, due to on-site conditions or other factors, a distribution cable run length exceeds this distance.
- Provide Plenum Rated Hook and Loop (Velcro) strapping for all cable bundles within all Communications Rooms.
