SECTION 27 15 13: Communications Copper Horizontal Cabling

category 5e 100 ohm balanced utp cable - Plenum

– GENERAL

Summary

SCOPE OF WORK

Category 5e 100 OHM balanced unshielded twisted pair (UTP) plenum horizontal cable is deployed through plenum pathways from the Telecommunications Room (TR) to the wall outlet at each workstation. Plenum cable is rated for air-ventilation spaces. Horizontal UTP cable is terminated into a modular jack in the wall outlet, and is punched into a cross-connect panel in the TR. This portion of horizontal cabling, including terminations, is defined as the permanent link. Standards permit one consolidation point inter-connection in the permanent link for zone cable distribution. Several codes and standards apply to installation and termination of 100 OHM balanced UTP cable. It is the responsibility of the cable installer to follow industry standards to assure proper cable performance and long-term reliability.

This section includes minimum requirements for the following:

      1. Horizontal pathways (conduit, cable tray, raceway, etc.) shall be fully deployed from the TR or TE to each wall plate location according to applicable codes and standards.

      2. Metallic horizontal cable pathways shall be bonded to an approved ground according to ANSI-J-STD-607.


    1. INSTALLATION

      1. Pull cable into conduits, or place into raceway or cable tray as specified. Do not exceed 25 Lb pull force per cable. Use appropriate lubricants as required to reduce pulling friction.

      2. All exposed wiring shall be installed in surface raceway.

      3. All wiring above ceilings or below access floors shall be installed in cable tray or open-top cable hangers.

      4. Cable slack and service loops shall be stored properly above the ceiling or under the access floor.

      5. Pathway fill ratio in conduit, tray, raceway, etc. shall not exceed 40% of pathway cross-sectional area.

      6. Installed cable bend radius shall be greater than 4X cable diameter. Avoid kinking or twisting the cable during installation.

      7. Do not over-tighten cable ties, and do not use staples or clamps to anchor cables. Velcro straps are recommended.

      8. Recommended spacing of cable supports above the ceiling shall be 48”.

      9. Maintain the following clearances from EMI sources:

        1. Power cable: 6 in.

        2. Florescent lights: 12 in.

        3. Transformers and electrical service enclosures: 36 in.

      10. Communications cabling that must cross power cables or conduit shall cross at a 90-degree angle, and shall not make physical contact.

      11. Length of each horizontal cable run from the TR to the wall outlet shall not exceed 90 meters.

      12. Leave sufficient slack for 90 degree sweeps at all vertical drops.

      13. Do not install cable in wet areas, or in proximity to hot water pipes or boilers.

      14. Cable ends for termination shall be clean and free from crush marks, cuts, or kinks left from pulling operations.

      15. Installed cable jackets shall have no abrasions with exposed conductor insulation or bare copper ‘shiners”. The installer is responsible to replace damaged cables.

      16. Horizontal cables extending from mounted jacks or panels shall maintain a minimum bend radius of at least 4 times the cable diameter.

      17. Firestop all cable penetrations through fire-rated barriers per local codes.

      18. For termination of panels in the TR, refer to Section 27 11 19: “Communications Termination Blocks and Patch Panels”.

      19. For termination of jacks in the wall outlet, refer to Section 27 15 43: “Communications Faceplates and Connectors”.


    1. FIELD QUALITY CONTROL – TESTING

      1. Cables are tested in the fully terminated condition, as part of the installed horizontal cabling system. Jacks in the wall outlet, and panels in the TR are to be terminated complete, with faceplates assembled complete and properly mounted.

      2. Each link or channel in the horizontal cabling system shall be identified and tested individually, using an industry standard level III tester with correct settings.

      3. Test cables in the horizontal channel or link for the parameters listed below.

      1. A “PASS” indication shall be obtained for each channel or link, using a level III tester. The installer is responsible to correct any test failures.

      2. Completed test reports shall be submitted per contract requirements of Division 01 Section 01 33 19: Field Test Reporting.

      3. See “Warranty” in Part 1 for provisions of the Hubbell link or channel full coverage warranty.
