Advantages of Fibre Optics

Why are fibre-optic systems revolutionising the market? When compared to conventional metal wire (copper wire), optical fibres are:

• Thinner - Optical fibres can be drawn to smaller diameters than copper wire. • Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires. • Less signal degradation - The loss of signal in optical fibre is less than in copper wire. • Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. • Low power - Because signals in optical fibres degrade less, lower- power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. • Digital signals - Optical fibres are ideally suited for carrying digital information. • Lightweight - An optical cable weighs less than a comparable copper wire cable. Fibre-optic cables take up less space. • Flexible - Because fibre optics are so flexible and can transmit and receive light, they are used in many flexible digital cameras for the following purposes: • Medical imaging - in bronchoscopes, endoscopes, laparoscopes

• Mechanical imaging - inspecting mechanical welds in pipes and engines (in airplanes, rockets, space shuttles, cars)

• Plumbing - to inspect sewer lines
