They are made from glass and are usually about 120 micrometres in diameter. Some of the most common everyday uses are in telecommunications, close-circuit television (CCTV) and cable television. Optical fibres carry signals more efficiently than copper cable and with a much higher bandwidth. This means that fibres can carry more channels of information over longer distances. Optical fibres cables are much lighter and thinner than copper cables with the same bandwidth. This means less space is needed in underground cabling ducts. Optical fibres are more expensive per metre than copper. However, one optical fibre can carry more signals than a single copper cable and the longer transmission distances mean that fewer expensive repeaters are required. Also copper cable uses more electrical power to deliver the signals. Optical fibres can’t be sliced as easily as copper cable. Employees need special training to handle the expensive splicing and measurement equipment.
