![]() ![]() Provides less protection from interference.Bandwidth is low when compared with Coaxial Cable.Disadvantages of Unshielded Twisted Pair Cable ![]() The wires are twisted together in a helical form to reduce electrical interference from similar pair. It consists of two insulating copper wires (1mm thick). Higher grades of UTP are used in LAN technologies like Ethernet.Cable with 2 pair use RJ-11 connector and 4 pair cable use RJ-45 connector.Īdvantages of Unshielded Twisted Pair Cable UTP cables consist of 2 or 4 pairs of twisted cable. Identification is the reason behind coloured plastic insulation. It is the most common type of telecommunication when compared with Shielded Twisted Pair Cable which consists of two conductors usually copper, each with its own colour plastic insulator. This results in a difference at the receiver. If the two wires are parallel, the effect of these unwanted signals is not the same in both wires because they are at different locations relative to the noise or crosstalk sources. In addition to the signal sent by the sender on one of the wires, interference(noise) and crosstalk may affect both wires and create unwanted signals. The receiver uses the difference between the two. One of these wires is used to carry signals to the receiver, and the other is used only as ground reference. Typical attenuation is 0.2 dB/Km 1kHz.Ī twisted pair consists of two conductors(normally copper), each with its own plastic insulation, twisted together.It is lightweight, cheap, can be installed easily, and they support many different types of network. This cable is the most commonly used and is cheaper than others. Optical fibre is a cable that accepts and transports signals in the form of light. Twisted-pair and coaxial cable use metallic (copper) conductors that accept and transport signals in the form of electric current. Guided media, which are those that provide a conduit from one device to another, include Twisted-Pair Cable, Coaxial Cable, and Fibre-Optic Cable.Ī signal travelling along any of these media is directed and contained by the physical limits of the medium.
