Fibre Optics Documents

Fibre optics or optical fibres are flexible, transparent fibres that are made by drawing glass or plastic to a diameter slightly thicker than that of a human hair. Optical fibres are used often as a means to transmit communications where they permit transport transmissions over longer distances at a higher bandwidth than electrical cables. Fibres are used instead of metal wires as they suffer far less transmission loss and the fibres are immune to electromagnetic interference. Fibre optics can also be used for illumination and images, this is accomplished by tying many fibres into a bundle.
