Fiber Optic Cables

Many organisations are replacing the older, copper wire cables in their networks with fiber Optic cables. Fiber optic cables use light as the communications medium. To create the on-and-off bit code needed by computers, the light is rapidly turned on and off on the channel. Fiber optic channels are light weight, can handle many times the telephone conversation or volumes of data handled by copper wire cabling, and can be
installed in environments hostile to copper wire, such as wet areas or areas subject to a great deal of electromagnetic interference. Data is more secure in fiber optic networks.
