multi-mode optical fiber
A type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Typical multimode links have data rates of 10 Mbit/s to 10 Gbit/s over link lengths of up to 600 meters (2000 feet) — more than sufficient for the majority of premises applications.

6 Gray, Elisha
SUBJECT AREA: Telecommunications[br]b. 2 August 1835 Barnesville, Ohio, USAd. 21 January 1901 Newtonville, Massachusetts, USA[br]American inventor who was only just beaten by Alexander Graham Bell in the race for the first telephone patent.[br]Initially apprenticed to a carpenter, Gray soon showed an interest in chemistry, but he eventually studied electrical engineering at Oberlin College, Oberlin, Ohio, in the late 1850s. In 1869 he founded the Western Electric Manufacturing Company, where he devised an electric-needle annunciator for use in hotels and lifts and carried out experimental work aimed at the development of a means of distant-speech communication. After successful realization of a liquid-based microphone and public demonstrations of a receiver using a metal diaphragm, on 14 February 1876 he deposited a caveat of intention to file a patent claim within three months for the invention of the telephone, only to learn that Alexander Graham Bell had filed a full patent claim only three hours earlier on the same day. Following litigation, the patent was eventually awarded to Bell. In 1880 Gray was appointed Professor of Dynamic Electricity at Oberlin College, but he appears to have retained his business interests since in 1891 he was both a member of the firm of Gray and Barton and electrician to his old firm, Western Electric. Subsequently, in 1895, he invented the TelAutograph, a form of remote-writing telegraph, or facsimile, capable of operating over short distances. The system used a transmitter in which the x and y movements of a writing stylus were coupled to a pair of variable resistors. In turn, these were connected by two telegraph wires to a pair of receiving coils, which were used to control the position of a pen on a sheet of paper, thus replicating the movement of the original stylus.[br]Bibliography1878, Experimental Research in Electro-Harmonic Telegraph and Telephony, 1867–76.Further ReadingJ.Munro, 1891, Heroes of the Telegraph.D.A.Hounshill, 1975, "Elisha Gray and the telephone.

12 Heaviside, Oliver
[br]b. 18 May 1850 London, Englandd. 2 February 1925 Torquay, Devon, England[br]English physicist who correctly predicted the existence of the ionosphere and its ability to reflect radio waves.[br]Brought up in poor, almost Dickensian, circumstances, at the age of 13 years Heaviside, a nephew by marriage of Sir Charles Wheatstone, went to Camden House Grammar School. There he won a medal for science, but he was forced to leave because his parents could not afford the fees. After a year of private study, he began his working life in Newcastle in 1870 as a telegraph operator for an Anglo-Dutch cable company, but he had to give up after only four years because of increasing deafness. He therefore proceeded to spend his time studying theoretical aspects of electrical transmission and communication, and moved to Devon with his parents in 1889. Because the operation of many electrical circuits involves transient phenomena, he found it necessary to develop what he called operational calculus (which was essentially a form of the Laplace transform calculus) in order to determine the response to sudden voltage and current changes. In 1893 he suggested that the distortion that occurred on long-distance telephone lines could be reduced by adding loading coils at regular intervals, thus creating a matched-transmission line. Between 1893 and 1912 he produced a series of writings on electromagnetic theory, in one of which, anticipating a conclusion of Einstein's special theory of relativity, he put forward the idea that the mass of an electric charge increases with its velocity. When it was found that despite the curvature of the earth it was possible to communicate over very great distances using radio signals in the so-called "short" wavebands, Heaviside suggested the presence of a conducting layer in the ionosphere that reflected the waves back to earth. Since a similar suggestion had been made almost at the same time by Arthur Kennelly of Harvard, this layer became known as the Kennelly-Heaviside layer.[br]Principal Honours and DistinctionsFRS 1891.
