TWISTED PAIR CABLES This type of cabling is used for telephone communications and most modern Ethernet networks. A pair of wires forms a circuit that can transmit data. A pair of wires forms a circuit that can transmit data. If the pair of wires are not twisted, electromagnetic noises (ex:motor), will effect the closer wire more, than the further one, therefore causing error. T wisted pairs are cables that are designed with two independent insulated wires wrapped around each other and with the goal to help to combat electromagnetic interference. A twisted pair cable comprises of two separate insulated copper wires , which are twisted together and run in parallel. The copper wires are typically 1mm in diameter. One of the wires is used to transmit data and the other is the ground reference. Twisted - pair cabling is often used in data networks for short and medium-length connections because o...
