Twisted pair cable

Another type of telephone cable is the twisted pair cable which contains a pair of copper wires- usually colour coded – that are twisted around each other. These cables have a diametre in the range of 0.4 to 0.8 mm. In each twisted pair cable, the number of twisted pairs can vary. In most cases, the higher the number of wire pairs, the better, because it reduces the risk of cross talk and any external noise. However, it is important to note that although twisted pair cables are incredibly cost-effective when compared to other telephone cables, they have a high attenuation and low bandwidth. There are essentially two types of twisted cables:

a. Unshielded twisted pair (UTP)

These twisted cables do not rely on a physical shield to block any connectivity issues or interference. This is the most common type of twisted pair cable used for both business and residential use. There are various UTPs that differ in their bandwidth as you go up the scale. Like a CAT1 scale has 1Mbps and CAT2 has a bandwidth of up to 2 Mbps.

b. Shielded twisted pair

The second type of twisted cable is the shielded twisted pair (STP). Unlike the unshielded twisted pair (UTP), the STP blocks external interference with foil jacket. This type of twisted cable is used on a larger scale for big enterprises and high-end applications that may be exposed to environmental elements.
