Backbone UTP/STP Copper Cable Installation | Inspection | Design
Installation
- Verify and ensure that equipment and cables are properly installed and in compliance with the Manufacturer’s requirements, Saudi Aramco Engineering Standards, Industry Codes and the Detailed Plan.
- Ensure and verify the cable size and type is in accordance with the approved IFC drawings prior commencing the cable pulling activities and shall conform to all applicable requirements, standards, and specifications prior to release to be used as part of
- Verify that the installed cable is as one of the four recognized and most suitable cable types that shall be used for backbone systems:
• 62.5/125 microns optical fiber or 50/125 microns multi mode optical fiber.
• Single mode optical fiber.
• 100 ohms balanced twisted pair CAT 6.
• 150 ohms shielded “ - Ensure that the total length of transmission cable between the TR cross-connect and the intermediate cross-connect is not exceeding 500 m (1640 ft) for data applications.
- Ensure that bonding and grounding of all non-network members of backbone cable and associated equipment is made to a TGB or TMGB.
- Ensure that Backbone cables are not spliced in pathways (raceways, conduits, trays, trunking) in ceilings and under raised floors.
- Verify cable splice points are placed in an area designated for cable splice closures in telecommunication room (entrance facility, equipment room or TR).
- Ensure the splice point is accessible to cable technicians at floor level and supported by cable racks.
- Verify that performance testing and inspection for Backbone Cabling (UTP, STP and Fiber Optic) and connectors is accomplished in accordance to SAES-T-634 (Telecommunications Cable Testing & Acceptance) EIA TIA-568A.
- Verify that electrical power cabling is not routed directly alongside communications cable (electrical cabling is usually in conduit, providing additional shielding).
- Verify that telecommunication cable is not placed within 1.8 m (6 ft) of any lightning protection system components.
- Ensure that a bonding conductor is installed along a non- shielded backbone cable pathway.
- Verify the proper backboard field termination color scheme.
Backbone UTP/STP Copper Cable Installation Acceptance Criteria
- Ensure that Solid State (electronic) arresters qualified by UL 497 is used within KAUST for primary protection devices when designing or constructing new facilities where the ground potential rise (GPR) does not exceed 350 V.
- Ensure that the required cable testing is performed and documented.
- Verify that identification cable tags are attached to each cable on each end.
- Verify that all cabling are tested and accepted for the category rating (category 6) of the cabling. Refer to EIA TIA-568A and EIA TSB-7 for required performance testing.
- Verify and ensure that the amount of untwisted for UTP cabling shall not exceed 13mm (0.5 inches) for CAT 6.
- Verify that all materials and debris are removed from the telecommunications facility and the construction site.
- Verify that if the transmission cable is 62.5 m Micron Fiber, then the maximum length from the closet to the main cross-connect is 2000m (6560 ft.) is not exceeded.
- Verify that all excess materials and debris are removed from the telecommunication facility and the construction site.
- Verify that connections between any two telecommunication closets shall not pass through more than three cross-connects (not including the cross-connects between the backbone and the horizontal wiring in the TCs.
- Verify the firestopping of the backbone system.
- Verify that if the transmission cable is 100-Ohm Unshielded Twisted Pair (UTP), then the maximum length from the closet to the main cross-connect is 800 m (2,630 ft) is not exceeded.
- Verify that if the transmission cable is Single-Mode Fiber, then the maximum length from the closet to the main cross-connect is 3,000 m (8,200 ft) is not exceeded.
- Verify that the methods used to properly secure vertical backbone cable is as one of the listed below :
• Brackets and Verticle cable racks
• Toggle bolts
• Clamps
• Straps (steel or plastic)
• Masonry hardware” - Ensure that backbone cables are not spliced in pathways (raceways, conduits, trays, trunking) in ceilings and under raised floors.
- Verify a bonding conductor is associated with non-shielded backbone cable.
