Twisted-pair wires and Coaxial Cable are the most commonly used transmission mediums, but are now recognized as old as the newer method of transmission takes over. Twisted-pair wire is the “most common transmission medium for Telephone and local area network connections. (Burd, 2001, 295)” The Twisted-pair wires are made up of two copper wires that are twisted around each other; the wires are normally enclosed in a non-conductive material eg plastic. This transmission mode is normally inexpensive but is very susceptible to noise.
and limited transmission capacity, due to the low bandwidth, which are generally less than 1 MHz and a relatively low voltage limit. The Coaxial Cable is a single strand of “insulated wire surrounded by a second wire made up of woven metal and a third plastic, outer covering. (Anderson. H, Christophersen. P, & Timmer-Arends. R, 1999, 236)” Due to the thick outer covering the Coaxial Cable has little electromagnetic interference therefore the bandwidth is relatively high of up to 50MHz the Coaxial Cable also has a relatively high data transmission capacity. The Coaxial Cable is normally used for Television due to the low susceptibility to noise. These two transmission mediums compared to The Fibre Optic Cable, have their advantages as Fibre Optic Cable has its disadvantages of being expensive and relatively difficult to install, therefore Twisted-pair wires and Coaxial cable is more cost effective to have and install. But on the other hand Fibre Optic Cable has a higher bandwidth and a very high resistance to electromagnetic interference and therefore data can be downloaded faster and will be more reliable, than that of the Twisted-pair wires and the Coaxial.
