developed the first LASER ( Light Amplification by Stimulated Emission of Radiation). * In 1967‚ Charles Kao and George Bockham of the Standard Telecommunications Laboratory proposed the cladded fiber cables. * In 1970‚ Robert Maurer‚ Donalk Keck and Kapron of Corning Glass developed the first fiber optics with losses less than 2dB/Km. * In 1980’s‚ losses in fiber optics were reduced to as low as 0.16 dB/Km.
