Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.
In telecommunications, fibre optic technology has virtually replaced copper wire in long-distance telephone lines, and it is used to link computers within local area networks. Fibre optics is also the basis of the fibrescopes used in examining internal parts of the body (endoscopy) or inspecting the interiors of manufactured structural products.
