COMMUNICATIONS STRUCTURED CABLING

PART 1 - GENERAL

1.1 DESCRIPTION

A. This section specifies modifications to an existing complete and operating voice and digital structured cabling dist ribution system, including associated equipment and hardware, in the facility.

1.2 SUBMITTALS

A. Certifications:

1. Test system cables and certify to Owner before proo f of performance testing can be conducted. Identify each cable as la beled on as-installed drawings.

2. Provide current and qualified test equipment OEM tr aining certificates and product OEM installation certifica tion for contractor installation, maintenance, and superviso ry personnel.

1.3 WARRANTY

A. As required by Owner.

PART 2 - PRODUCTS

2.1 PERFORMANCE AND DESIGN CRITERIA

A. Provide complete system including fiber optic distr ibution cables, connectors, and all equipment necessary for a compl ete and functional system.

B. Industry Standards:

1. Provide supplies and materials listed by a national ly recognized testing laboratory where such standards are establi shed for supplies, materials or equipment.

C. System Performance: Provide complete system to meet or exceed that in use at the facility.

D. Terminate all interconnecting twisted pair, fiber-o ptic or coaxial cables on patch panels or punch blocks. Terminate u nused or spare conductors and fiber strands. Do not leave unused o r spare twisted pair wire, fiber-optic or coaxial cable unterminated, un connected, loose or unsecured.

E. Color code distribution wiring to conform to ANSI/T IA 606-B and construction documents, whichever is more stringent . Label all equipment, conduit, enclosures, jacks, and cables o n record drawings, to facilitate installation and maintenance.

F. In addition to requirements in Section 27 05 11, RE QUIREMENTS FOR

COMMUNICATION INSTALLATIONS, provide stainless stee l faceplates with plastic covers over labels.

2.2 EQUIPMENT AND MATERIALS

A. Cable Systems - Twisted Pair, Fiber optic, Coaxial and Analog:

1. General:

a. Provide cable (i.e. backbone, outside plant, and ho rizontal cabling) conforming to accepted industry standards with regards to size, color code, and insulation.

b. Some areas can be considered “plenum”. Comply with all codes pertaining to plenum environments. It is contractor ’s responsibility to review the cable requirements wit h Owner prior to installation to confirm type of environment pres ent at each location.

c. Provide proper test equipment to confirm that cable s meet each

OEM’s standard transmission requirements, and ensur e cable carries data transmissions at required speeds, freq uencies, and fully loaded bandwidth.

2. Fiber Optic Backbone Cable:

a. Provide 62.5/125 micron OM4 multi-mode cable, conta ining strands of fiber of type matching existing conditions.

b. Terminate multimode fibers at both ends with connec tors suitable to connect to existing equipment. Provide minimum 6 10 mm (2 ft.)

cable loop at each end.

c. Test all fiber optic strands' cable transmission pe rformance in accordance with TIA standards. Measure attenuation in accordance with fiber optic test procedures TIA-455-C ('-61', or -53).

Provide written results to Owner for review and app roval.

B. Conduit and Signal Ducts:

1. Conduit:

a. Provide conduit or sleeves for cables penetrating w alls, ceilings, floors, interstitial space, fire barriers , etc.

b. Minimum Conduit Size: 19 mm (3/4 inch).

c. Provide separate conduit and signal ducts for each cable type installation.

d. Maximum 40 percent conduit fill for cable installat ion.

2. Signal Duct, Cable Duct, or Cable Tray: Use existin g signal duct, cable duct, and cable tray, when identified and acc epted by Owner.

PART 3 - EXECUTION

3.1 INSTALLATION

A. Install for ease of operation, maintenance, and tes ting.

B. Install system to comply with NFPA 70 National Elec trical Code and original equipment manufacturers' (OEM) installatio n instructions.

C. Labeling:

1. Industry Standard: Provide labeling to match that i n use at the facility.

3.2 FIELD QUALITY CONTROL

A. Interim Inspection:

1. Verify that equipment provided adheres to installat ion requirements of this section.

2. Perform fiber optical field inspection tests via at tenuation measurements on factory reels and provide results a long with manufacturer certification for factory reel tests. Remove failed cable reels from project site upon attenuation test failure.

B. Acceptance Test:

1. Schedule an acceptance test date and give Owner 30 days' written notice prior to date acceptance test is expected to begin.

2. Test only in presence of Owner.

3. Test utilizing approved test equipment to certify p roof of performance.

4. Verify that total system meets the requirements of this section.

C. Verification Tests:

1. Multi-mode Fiber Optic Cable: Perform end-to-end at tenuation tests in accordance with TIA-568-B.3 and TIA-526-14A usin g // Method A, Optical Power Meter and Light Source // and // Meth od B, OTDR //.

Perform verification acceptance test.

D. Performance Testing:

1. Fiber Optic Links: Perform end-to-end fiber optic c able link tests in accordance with TIA-568-B.3.

E. Total System Acceptance Test: Perform verification tests for fiber optic cabling systems after complete telecommunicat ion distribution system and workstation outlet are installed.
