1966 The Year of Fiber Optic Communication
Kao and George Hockham proposed optical fibers at STC Laboratories (STL) at Harlow, England, when they showed that the losses of 1000 dB/km in existing glass (compared to 5-10 dB/km in coaxial cable) was due to contaminants, which could potentially be. They have exhibited an information-carrying capacity of one Gigacycle, which is equivalent to about 200 television channels or over 200,000 telephone channels. Dates, of course, are often approximate, as putting a firm date on the introduction of a new technology is often impossible! the most important. Kao, who works for the British Standard Telecommunications Experimental Ltd, together with his colleague G. Hockham, published a paper： " Dielectric-fibre surface waveguides for optical frequencies ".
