**FIBER OPTIC CABLES**
The designers of the Internet wanted to make certain that nothing could stop the flow, not even a nuclear attack, so they specified a highly desentralized network with multiples connections between the various computers. The central heart of the Internet - called "the backbone" - consists of many university, corporate and goverment networks, connected together via thick bundless of glass filaments, called **FIBER OPTIC CABLES**. is a glass or plastic fiber that carries light along its length.

Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
