What is Structured Cabling?
A structured cabling system (SCS) is a set of cabling and connectivity products
that integrates the voice, data, video, and various management systems of a
building
Benefits of Structured Cabling
• Consistency & Cost reduction
• Support for multi-vendor equipment
• Simplify moves/adds/changes
• Simplify troubleshooting
• Support for future applications
• Fault Isolation

Elements of Structured Cabling Systems
• Entrance Facilities
• Equipment Rooms
• Backbone Cabling
• Horizontal Cabling
• Telecommunications Rooms or Telecommunications
Enclosure
• Work-Area
Entrance Facilities
• Contain the cables, network demarcation
point(s), connecting hardware, protection
devices and other equipment that connect
to the access provider (AP) or private
network cabling.
• Includes connections between outside
plant and inside building cabling.
Equipment Rooms
The environmentally controlled
centralized space for
telecommunications equipment is
usually more complex than a
telecommunications room (TR) or
telecommunications enclosure (TE).
Backbone Cabling
The backbone cabling provides
interconnection between
telecommunications rooms,
equipment rooms, access
provider (AP) spaces and
entrance facilities.
Backbone Cabling
• The wiring used for backbone cabling may be either copper or fiber optic.
• Recommended backbone cable maximum distance limitations include:
• · Voice grade 100 ohm UTP 800 meter limitation
• · STP data grade 150 ohm 90 meter limitation
• · Multimode 62.5/125μm fiber 2,000 meter limitation
• · Patch cable 3 - 6 meter limitation
Horizontal Cabling
The horizontal cabling system
extends from the work area’s
telecommunications information
outlet to the telecommunications
room (TR) or
telecommunications enclosure
(TE).
Telecommunications Room
A Telecommunications Room
houses the terminations of
horizontal and backbone
cables to connecting
hardware including any
jumpers or patch cords.
Work area
Work area (WA) components
extend from the
telecommunications
outlet/connector end of the
horizontal cabling system to
the WA equipment.
UTP Color Coding
To distinguish between pairs, they are colored each pair has designated
Tip and Ring conductors. Pair 1 can therefore be designated T1 and R1.
Both UTP & STP conform to this standard
• T1 - White Blue/Blue White - R1
• T2 - White Orange/Orange White - R2
• T3 - White Green/Green White - R3
• T4 - White Brown/Brown White - R4

Editor's Notes

  • #5 Consistency & Cost reduction: A structured cabling systems means the same cabling systems for Data, voice and video. A structured approach in cabling also helps reduce maintenance costs 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. Fault Isolation: By dividing the entire infrastructure into simple manageable blocks, it is easy to test and isolate the specific points of fault and correct them with minimal disturbance to the network.
  • #9 Entrance Facilities is the point where the telephone company network ends and connects with the on-premises wiring at the customer premises. Equipment Rooms house equipment and wiring consolidation points that serve the users inside the building or campus. Backbone Cabling connects between the equipment/telecommunications rooms, so named because the rooms are typically on different floors. Horizontal Cabling wiring can be IW (inside wiring) or Plenum Cabling and connects telecommunications rooms to individual outlets or work areas on the floor, usually through the wireways, conduits or ceiling spaces of each floor. Telecommunications Rooms or Telecommunications Enclosure connects between the backbone cabling and horizontal cabling. Work-Area Components connect end-user equipment to outlets of the horizontal cabling system.
  • #10 The building entrance requirements are simply the specifications for the point at which the cabling enters a building. The specifications include recommendations for the type of connecting and surge protection devices. The standard also specifies the placement of the cabling used to connect the inside wiring to other buildings.
  • #11 The equipment room is typically the existing telecommunications closet. It can be any secure storage area where the communications racks, cables, and other more expensive hardware devices, such as patch panels, hubs, switches, and routers are located.
  • #12 Backbone cabling is the wiring that runs vertically between floors and/or between equipment rooms. Backbone cabling provides the interconnections between equipment rooms and the building entrance site, including cross-connects, patch cords, and terminators. Backbone cabling can also extend between buildings
  • #14 Horizontal cable is the physical media that runs from the wall jack at the workstation outlet to the termination in the equipment room. It also includes the cable run from the wall outlet to the workstation, and the cable in equipment closets that connects hubs, switches, and so on. These short pieces of cable are called patch cords or patch cable. There is a 3- meter limit from the wall jack to the workstation and a 6-meter limit between equipment in the telecommunications closet
  • #16 The work area components include the computers, telephones, patch cables, adapters, and so on. Workstations are connected to the wall outlet by patch cables.
