Five Subsystems That Make Up Structured Cabling in Your Business Premises

Computers and communication devices are an integral part of modern businesses. Gone are the days when you had to walk from one office to the other to deliver a message to colleagues or to people in other departments. Today, a business can rely on local computer networks with multiple devices to facilitate communication and monitoring services. The network is typically comprised of a cabling system for transmitting signals from one device to the other until the recipient receives information in a manner they can understand. Such data cabling communities normally have five subsystems, which are discussed here for your understanding:

Entrance Facility

Just as the name suggests, the entrance facility is the point where the cabling on your premises meets public network cables or cables by an external network's company. The entrance point is comprised of an antenna and special transmission lines needed to upgrade or downgrade signals to a certain intensity that suits your specific needs. The entrance point connects the competitive local networks to the incumbent facilities on your premises.

Equipment Rooms

Equipment rooms house all the consolidation points of the cables that serve the premises. The equipment rooms are the points of origin for all the cables on the premises. They also hold auxiliary antennas used to enhance signal transmission.

Backbone Cabling

Backbone cabling is the heart of the wiring system. These are the intra-building and inter-building connections that link the entrance facilities, telecommunication closets, and the equipment rooms. Typically, these cables run from one floor to the other, which is one reason why they are referred to as vertical cabling. You can use several types of cables for the vertical cabling in your premises. These include the following:

  1. Unshielded twisted pair (UTP) cables – UTP cables have two unshielded wires intertwined around each other. They are low cost and effective when used in local area networks.
  2. Fibre optic cable – these cables have an assembly that's similar to an electrical cable with additional fibres for carrying light. They are excellent at the high-speed transmission of data.
  3. Coaxial cables – coaxial cables have inner conductors enclosed in tubular insulating layers. In most cases, the conductor cores are made from copper, which makes them good for carrying high-frequency electrical signals.

Horizontal Cabling

Horizontal cabling forms the distribution networks that branch from the backbone cabling. These wires penetrate the individual rooms and connect the backbone cabling and end-user devices.

Work Area Devices

Work area components are comprised of the devices that translate signals into information that end users can understand. They include computer monitors, telephones, warning alarms and other things.
