Structured Cabling Design


Designing Structured Wired Systems for telephone and cable network in any building with centralized distribution in the special rooms, (Server Rooms) is a most responsible part of the SYSTEM CONSULTING. We provide detailed system specifications; perform an analysis of the specifications and preliminary plans to determine if any improvements or changes are necessary.

The Structured Cabling System include the following components:

1. Local Area Network Cabling Infrastructure: The network-cabling infrastructure design utilizes a star topology consisting of horizontal cabling, backbone cabling, and various telecommunications cabling pathways and spaces. Design-engineering services required to determine the best route and method for cable conveyance throughout the buildings in accordance with project requirements and applicable installation standards.
2. Backbone Cabling - As a minimum design includes indoor-outdoor, riser rated hybrid multi-mode/single-mode fiber optic cable. Connectors, distribution panels, ferrules, enclosures, and consumables included into design to provide the backbone connectivity between network distribution frames. Designer provides calculations and drawings illustrating distance limitations.
3. Horizontal Cabling – Usually each data outlet consist of either one Category 6 cable or four strands of fiber optic cable.
4. Structured Cabling Design includes a minimum of one Main Distribution Frame (MDF). Depending upon the size of the facility, one or more Intermediate Distribution Frames (IDFs), Local Distribution Frames (LDF) and one Limited Distribution Cabinet (LDC) could be planned. Telecommunications spaces should be located in secure areas with proper ventilation, HVAC, power, lighting, and grounding. MDFs and IDFs shall accommodate horizontal and backbone cabling termination equipment including: 19-inch free standing racks, wall-mounted racks, or cabinets, patch panels, vertical and horizontal wire management, patch cables, ladder racking, conduit sleeves, and data electronics. Also, MDF shall be located as close to the Minimum Point of Entry (MPOE) as practical.
5. WAN Cabling: If the MPOE is in a separate room from the MDF, Furnished cabling between the MDF cabinet and the MPOE shall be planned.
6. Cabinet locations shall provide sufficient working space around panels to comply with the California Electrical Code and the BICSI TDMM current edition.
7. The telephone wiring system consists of distribution and feeder cables that permit connection of telephone handsets or other interfacing devices, through cross connecting panels, back to connecting blocks associated with an Owner-furnished, Owner installed PBX System.
8. The quantity of Telephone System cabling shall be designed based upon the size and scope of the project, or in accordance with drawings furnished by a designer.
9. Equipment specifications for the Project site indicated on Drawings, the scope of work, and/or as specified herein.
10. Underground service entrances are required for connections to:
Telephone Service Provider and Community Antenna Television (CATV) Access Provider.
