Information on Fibre Optic Cable
A fibre optic cable is constructed by enclosing a thin glass fibre core in a glass cladding and surrounding the result in a protective jacket. Electrical signals are translated into light pulses by modulating a laser, and are detected at the receiver by photo-electric diodes. A waveguide for the optical frequencies is provided by the difference between the refractive indices of the cladding and the glass core.
