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