What is Twisted Pair Cable?
A twisted pair consists of a pair of insulated wires twisted together. It is a cable type used in telecommunication for very long time. Cable twisting helps to reduce noise pickup from outside sources and crosstalk on multi-pair cables.
Twisted pair cable is good for transferring balanced differential signals. The practice of transmitting signals differentially dates back to the early days of telegraph and radio. The advantages of improved signal-to-noise ratio, crosstalk, and ground bounce that balanced signal transmission bring, are particularly valuable in wide bandwidth and high fidelity systems.
Types of Twisted Pair
The two types of twisted pairs are:
1. Unshielded twisted pair (UTP)
2. Shielded twisted pair (STP)
Unshielded Twisted Pair (UTP)
The most commonly used form of twisted pair is unshielded twisted pair (UTP). It is just two insulated wires twisted together; it consists of color-coded copper wires, but does not include any foil or braiding as insulator to protect against interference; Wire pairs within each cable have varied amounts of twists per foot to produce cancellation; There are different categories of UTP; The following tabe shows the UTP categories, the No. of pairs in each, and the grade of cable each uses and how they are implemented.

Shielded Twisted Pair (STP)

Shielded Twisted Pair
Shielded Twisted Pair (STP) cable is used to eliminate inductive and capacitive coupling. Twisting cancels out inductive coupling, while the shield eliminates capacitive coupling. Most applications for this cable are between equipment, racks and buildings. Shielding adds usually some attenuation to the cable (compared to unshielded), but usually not because in the case of balanced transmission, the complementing signals will effectively cancel out any shield currents, so shield current losses are negligible.
