The difference between cable and fiber are there?

     Cable, the cable is generally considered by one or more mutually insulated conductors and a protective layer made ​​of an insulating outsourcing, or information that the power transmitted to the wire from one another. Refers broadly to the metal means for transmitting the electrical signal medium.
     By definition, a cable is used to electrically conductive. Generally consists of the following metal:
     Second only to silver conductive copper, thermal conductivity second only to gold and silver; corrosion-resistant, non-magnetic, plastic, easy to weld, and versatile. Copper alloys are mainly in order to improve the wear resistance of copper, corrosion resistance and mechanical properties.
     Silver metallic conductivity and thermal conductivity up, with good corrosion resistance and oxidation resistance, easy welding; mainly used for coating and the cladding layer;
     Gold, nickel, used as the high temperature wire.
     Iron (steel), often reinforcing materials for composite conductors, as compared with steel core aluminum wire, copper clad steel, aluminum clad steel wire and so on.
     Zinc, used to make steel / steel / iron-plated conductors with to prevent corrosion.
     Tin, used steel / copper plating to prevent corrosion with, and contribute to the copper welding.


     The short fibers are optical fibers, optical transmission tool is total internal reflection of light in the fiber using a glass or plastic and in the reached. Before the Chinese University of Hong Kong Kao and George A. Hockham proposed optical fiber can be used for first conceived communication transmission, Kao and therefore get the Nobel Prize in Physics in 2009.
     Transmitting means at one end of an optical fiber using a light emitting diode (light emitting diode, LED) or a laser light pulse is transmitted to the other end of the optical fiber receiving means, the photosensitive member using the optical fiber detection pulse.
     In daily life, due to much lower light transmission loss of the optical fiber than the electrical conduction losses in the cable, the optical fiber is used as a long distance transmission of information.
