Cabling

In 1997, unable to find local vendors who could or would deliver consistent high quality cabling installations, Canyon Telecom founded a structured cabling division dedicated to supporting the low voltage communications needs of our clients with the same commitment to quality, pride in work and exceeding customer expectations as our telecommunications division.

We specialize in:

  • Voice and Data Cabling
  • Category 3
  • Category 5 & 5e
  • Category 6 & 6a
  • Category 7
  • Fiber Cabling
  • Multimode Fiber 62.5/125um
  • Singlemode Fiber
  • Video Cabling
  • RG6 for CATV
  • Siamese RG59 and 18/2 for Video Surveillance
  • Overhead Paging
  • 18/2 cable

What is Structured Cabling

Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications, using category 5 (CAT 5E), category 6 cable (CAT 6), (CAT 6A), category 7 cable (CAT 7), and Fiber Cable. These standards define how to lay the cabling in a star formation, such that all outlets terminate at a central patch panel (which is normally 19 inch rack-mounted), from where it can be determined exactly how these connections will be used. Each outlet can be 'patched' into a data network switch (normally also rack mounted alongside), or patched into a 'telecoms patch panel' which forms a bridge into a private branch exchange (PBX) telephone system, thus making the connection a voice port.

The advantages of Structured Cabling are:

  • Consistency - A structured cabling systems means the same cabling systems for data, voice and video.
  • Support for multi-vendor equipment - A standard-based cable system will support applications and hardware even with mix & match vendors.
  • Simplify moves/adds/changes - Structured cabling systems can support any changes within the systems.
  • Simplify troubleshooting - With structured cabling systems, problems are less likely to down the entire network, easier to isolate and easier to fix.
  • Support for future applications - Structured cabling system supports future applications like multimedia, video conferencing etc with little or no upgrade pain.

Structured Cabling System Design Considerations:

The six subsystem of a Structured Cabling System are as follows:

  1. Building Entrance - Building entrance facilities provide the point at which outside cabling interfaces with the intrabuilding backbone cabling. The physical requirements of the network interface are defined in the EIA/TIA-569 standard.
  2. Equipment Room - The design aspects of the equipment room are specified in the EIA/TIA-569 standard. Equipment rooms usually house equipment of higher complexity than telecommunication closets. An equipment room may provide any or all of the functions of a telecommunications closet.
  3. Backbone Cabling - The backbone cabling provides interconnection between telecommunications closets, equipment rooms and entrance facilities. It consists of the backbone cables, intermediate and main cross-connects, mechanical terminations and patch cords or jumpers used for backbone-to-backbone cross-connection. This includes:
    • Vertical connection between floors (risers)
    • Cables between an equipment room and building cable entrance facilities
    • Cables between buildings (inter-building)
    TIA Backbone Cable Distance
    • Singlemode Fiber - 3000m(9840ft)
    • 62.5/125um Multimode Fiber - 2000m(6560ft)
    • UTP Copper Applications - 100m(328ft)
  4. Telecommunications Closet - A telecommunications closet is the area within a building that houses the telecommunications cabling system equipment. This includes the mechanical terminations and/or cross-connect for the horizontal and backbone cabling system.
  5. Horizontal Cabling - The horizontal cabling system extends from the telecommunications outlet in the work area to the horizontal cross-connect in the telecommunications closet. It includes the telecommunications outlet, an optional consolidation point or transition point connector, horizontal cable, and the mechanical terminations and patch cords (or jumpers) that comprises the horizontal cross-connect. The horizontal cabling shall be configured in a star topology; each work area outlet is connected to a horizontal cross-connect(HC) in a telecommunications closet(TC). Note: From end to end the total cable length must not exceed 100 meters. 90 meters of horizontal cable, and a total of 10 meters is allowed for work area and telecommunications closet patch and jumper cables.
  6. Work Area - The telecommunications outlet serves as the work area interface to the cabling system. Some specifications related to work area cabling include:
    • Equipment cords are assumed to have the same performance as patch cords of the same type and category
    • When used, adapters are assumed to be compatible with the transmission capabilities of the equipment to which they connect. Horizontal cable lengths are specified with the assumption that a maximum cable length of 3m (10ft)
    Work Area Components
    • Station Equipment computers, data terminals, telephones, etc.
    • Patch Cables modular cords, PC adapter cables, fiber jumpers, etc.
    • Adapters baluns, etc. must be external to telecommunications outlet is used for equipment cords in the work area.

Note: For establishing maximum horizontal link distances, a combined maximum length of 10m (33ft) is allowed for patch cables (or jumpers) and (or equipment cables in the work area and the telecommunications.
