What is Twisted Pair Cabling

As a variety of data processing equipment is added to a company's inventory, management acknowledges that the units must be tied together for better use and economy. This may lead most companies to integrate the equipment into a centralized network.


When a computer, printer, telephones, and plotters are plugged into one centralized area, it's called a Local Area Network (LAN). The installation of a LAN requires specialized wiring to ensure that each unit is working accordingly.


There are many types of different cables to choose from, depending on your business needs. Today we will focus on copper twisted-pair cabling.


Unshielded Twisted-Pair (UTP) Cabling

Today, Twisted-Pair Cabling used by much of the telephone and telecommunications industries. It consists of two insulated copper wires, which twisted about 20 turns per foot. The majority of telephone cables of strong # 24-gage copper wire, each coated and twisted in a pair. The most common cabling contains two pairs of wires in a tight outer jacket.

Each of the wires is color-coded, the color that is used is red, green, black, and yellow. With the telephone, only two of the wires are needed, which leaves the other cables available for a second line or other functions. A technician must use the correct coding when installing or testing cables


Shielding of Transmissions Lines

Shielding is an essential part of installing any cabling and creates a low signal-to-noise ratio within the equipment. The grounds for the material must be tested when new equipment is installed, or equipment is moved.


Shielding is most effective when shielding every pair of cables. Shielding for telecommunication cables should only be grounded at the source to be most successful. If shielding is efficient in reducing electromagnetic radiation from data transmission wires and collecting from other sources, it would seem. However, shield grounding at both ends generates an electrical path through the ground path between the equipment is called a ground loop and results in a potential difference (voltage) between the source and the destination equipment. A ground loop can cause the line to pick up noise.

What is the advantage of Twisted-Pair Cabling?

An advantage of a twisted pair can be used with coax or fiber cabling

What is the disadvantage of Twisted-Pair Cabling?

One disadvantage is that the higher the carrier frequency, the greater the amplitude of the signals. This results in the need for repeaters to amplify the signal along long lines.
