cable systems

A coaxial cable consists of an inner conductor and an outer conductor, separated by a dielectric insulating material. The inner conductor is made of a copper wire encased inside the dielectric material. As for the outer conductor, it is made of copper, tinned copper, or copper-coated ste..

Question: Name the following: 1) A molten metal that catches fire in chlorine gas and gives off white fumes 2) A metal that forms two types of oxides and rusts in moisture; write their formulae also 3) A metal used in hot water systems 4) A metal used in long distance cables..

.e., facsimile of printed matter or pictures) use a similar mechanism. In the case of intercontinental telecommunication, two or more satellites are linked together. High frequency radio and submarine cable systems have been widely used for long- distance overseas telecommunicat..

The transmission lines used in telephony are of two kinds: open- wire and cable. The open-wire lines are gradually being superseded by cable construction, either overhead or underground, for two principal reasons. In the first place, many more circuits can be accommodated-there ..

An optical fiber is a dielectric wave guide that transports light signals from one place to another just as a twisted-wire pair or a coaxial cable transports electrical signals. It consists of a central core within which the propagating electromagnetic field is confined and which is surro..

. Telephone and telegraph wires; audio, video, and radio cables; and the myriad nerve fibers in our bodies are all transmission lines. The interconnections of all electric circuits are transmission lines, and in a broad sense waveguides and optical fibers, and even radio links maybe regar..
