Category 6 Cabling System City of Sunny Isles Beach Request for Proposal Confidential and Proprietary • The combined length of jumpers, or patch cords and equipment cables in the telecommunications room and the work area should not exceed 10m (33 ft) unless used in conjunction with a multi -user telecommunications outlet. • Two horizontal cables shall be routed to each work area. At least one horizontal cable connected to an information outlet shall be 4 -pair, 100 Q balanced twisted -pair. • It is recommended that a minimum horizontal cable distance of 15m (49 ft.) shall be maintained between the telecommunications room and the work area. • Horizontal pathways shall be installed or selected such that the minimum bend radius of horizontal cables is kept within manufacturer specifications both during and after installation. • In open ceiling cabling, cable supports shall be provided by means that is structurally independent of the suspended ceiling, its framework, or supports. These supports shall be spaced no more than 1.5 m (5 ft) apart. • Telecommunications pathways, spaces and metallic cables, which run parallel with electric power or lighting, which is less than or equal to 480 Vrms, shall be installed with a minimum clearance of 50 mm (2 in). • The installation of telecommunications cabling shall maintain a minimum clearance of 3 m (10 ft) from power cables in excess of 480 Vrms. • No telecommunications cross - connects shall be physically located within 6 m (20 ft) of electrical distribution panels, step down devices, or transformers, which carry voltages in excess of 480 Vrms. • For voice or data applications, 4 -pair balanced twisted -pair or fiber optic cables shall be run using a star topology from the telecommunications room serving that floor to every individual information outlet. The customer prior to installation of the cabling shall approve all cable routes. • The Contractor shall observe the bending radius and pulling strength requirements of the 4 -pair balanced twisted -pair and fiber optic cable during handling and installation. • Each run of balanced twisted -pair cable between horizontal portions of the cross - connect in the telecommunication closet and the information outlet shall not contain splices. • In a false ceiling environment, a minimum of 3 inches (75 mm) shall be observed between the cable supports and the false ceiling. • Continuous conduit runs installed by the contractor should not exceed 30.5 m (100 ft) or contain more than two (2) 90 degree bends without utilizing appropriately sized pull boxes. • All horizontal pathways shall be designed, installed and grounded to meet applicable local and national building and electrical codes. • Maximum conduit pathway capacity shall not exceed a 40% fill. However, perimeter and furniture fill is limited to 60% fill for move and changes. • Horizontal distribution cables shall not be exposed in the work area or other locations with public access. • Cables routed in a suspended ceiling shall not be draped across the ceiling tiles. Cable supports shall be mounted a minimum of 75 mm (3 in) above the ceiling grid supporting the tiles. 10.2.4 WORK AREA TERMINATION ■ All balanced twisted -pair cables wired to the telecommunications outlet/connector, shall have 4 -pairs terminated in eight - position modular outlets in the work area. All pairs shall be terminated using a EIA/TIA 568 -b Wiring Scheme. ■ The telecommunications outlet/connector shall be securely mounted at planned locations. ■ The height of the telecommunications faceplates shall be to applicable codes and regulations. 10.2.5 PULLING TENSION ■ The maximum cable pulling tensions shall not exceed manufacturer's specifications.
