Optical fiber

Thin glass, silicia or plastic wires, building the interstructure base for data transmission. An optical fiber cable contains several individual fibers, and each of them is capable of driving a signal (light impulse) at illimited bandwidth. Optical fibers are usually employed for long-distance communication. they can transfer "heavy" data loads, and the signal reaches the recipient, protected from possible disturbances along the way. The driving capacity of optical fibers is higher than the traditional cable ones.
