b. Under each individual jack, the 4-digit cable number.

2. All jacks in a single device plate must have sequential cable numbers.

This room number must be the permanent room numbers assigned by the Owner, not the construction room numbers. The room designation shall be placed above the jacks in the panel.

2. Below each jack in every patch panel, the 4-digit cable number representing that jack. All cable numbers in all patch panels must be sequential.

3. Label shall be typewritten label tape, 3/8-inch-wide with industrial strength adhesive.

3.06 TERMINATION HARDWARE

A. Quantities of termination blocks, racks, splice enclosures, and patch panels, etc. shown on Drawings are illustrative only and are meant to indicate the general configuration of the work. The Contractor is responsible for providing the correct quantities of termination




hardware required to terminate, patch, cross connect, etc. the volume of cable described herein and shown on the Drawings. Rack quantities shall be no less than what is shown on the Drawings.

B. At all times during the construction, the Contractor shall protect the equipment from damage and theft. Equipment shall not be installed until such time as other trades have completed their work in the area.

3.07 TELECOMM ROOMS

A. Contractor is responsible for providing earthquake bracing and support for all racks installed in telecommunications rooms.

B. Each relay rack must have front facing vertical wire management chases installed on each side of the rack.

3.08 CROSS-CONNECT

A. Perform all cross-connects and patching.

B. Furnish cross connect cables and perform all necessary cross-connect and patches as indicated in these specifications. Utilize cross-connect wire, and 25 pair cable as necessary. Cut all cross-connect wire to length, leaving enough slack to form a “3-finger loop”. After completion of work, dress patch cords and cross-connect wire in cable management apparatus. Do not tie-wrap cross-connect wires into bundles. The Contractor is responsible for all cross-connect schedules and documentation to the Owner/Consultant on completion of project. Patch cables shall be same brand as the patch panel jacks.

C. Telecommunication entrance room: Cross-connect all pairs of the “voice” station cable to the “voice” backbone.

3.09 GROUNDING

A. All metallic cable tray, ladder rack, raceways, cable sheath/armor, enclosures, and equipment racks and other conductive surfaces shall be properly bonded to the grounding system. All paint and other coatings shall be removed at all contact surfaces to ensure proper ground.

B. Furnish and install an insulated #6 copper ground wire from all telecommunication rooms to the main building electrical ground point in the main electrical room. Drawing notes indicating a larger size shall take precedence.

C. Ground all cable shields, ducts, connector panels and grounding blocks.

D. All grounding shall be in compliance with the NEC code Article 800, Article 250, as well as EIA/TIA standard 607.

3.10 CABLE TESTING

A. Copper:

1. Visually inspect all cables, cable reels, and shipping cartoons to detect cable damage incurred during shipping and transport. Return visibly damaged items to the manufacturer.

2. Conduct cable testing as described below upon completion of installation. Test fully completed systems only. Piecemeal testing is not acceptable, except by prior written approval from the Architect.

3. After terminating both ends, but before any cross connects are installed, test all UTP voice and data stations cables for attenuation and for near-end cross talk (NEXT) to 100 Mhz. Test all UTP backbone, distribution and patch cable for cable pair/conductor




continuity, ground fault, proper cross-connect, shorts, loose connectors, and crossed pairs.

4. Remove all defective cables from pathways system. Do not abandon cables in place.

B. Fiber:

1. Visually inspect all fiber, fiber reels, and shipping cartons to detect cable damage incurred during shipping and transport. Return visibly damaged items to the manufacturer.

2. Conduct fiber testing as described below upon completion of installation. Test fully completed systems only. Piecemeal testing is not acceptable, except by prior written approval from the Architect.

3. After installation of connectors, visually inspect each fiber end-face at 10x magnification. Refinish fibers with visible defects and/or variations in the core area.

4. Perform end-to-end, bi-directional attenuation (loss) test for each fiber strand at 850 nm and 1300nm wave lengths. Conduct tests in accordance with EIA/TIA-526-14, method B and with test instrument manufacturers printed instructions test equipment must have calibration certificate.

5. Demonstrate that measured link loss does not exceed the “worst case” allowable loss, which is the sum of: the connectors loss (based on the number of mated connector pairs at the EIA/TIA-568 maximum allowable loss of 3.75 db/km @ 850nm and 1.5dB/km @ 1300nm).

6. Strands whose measured attenuation falls outside the acceptable range shall be subject to further inspection and testing to determine the nature of the fault. At a minimum, an OTDR shall be used to determine the true loss for each connector pair, the exact length of the fiber, and to identify the presence of any core damage.

7. Faults related to connectorization shall be corrected, and the fiber re-tested as stated in the paragraph above until acceptable attenuation measurements are recorded.

8. Where defects are found to be inherent in the fiber itself, fiber must be removed and replaced. Also, replace any cable having fewer than the manufacturers guarantee number of serviceable fibers.

9. Remove all defective cables from pathways system. Do not abandon cables in place.

10. The Architect reserves the right to observe the conduct of any or all portions of the testing process.

11. All test results and corrective procedures are to be documented and submitted to the Owner within fourteen (14) working days of test completion.

3.11 ACCEPTANCE

A. Upon receipt of the Contractor’s documentation of cable testing, the Architect will review the installation and may request a retest using contractor equipment and labor, of up to 5% of the cable/wires installed.
