			Optical fibers are transparent glass or plastic tubes that carry information encoded light. Other fiber optic cables are used to transmit intense light to pump lasers or for remote imaging such as a boroscope.

	Visible light has a frequency of 10<sup>14</sup> Hz. A light signal can be ~~modulate~~ at much higher frequencies than either radio or micowave. The movement from electrons to photonics is driven by the desire to create communication channels using high frequency carriers and which have extremely high information content . This requires that light be guided and controlled in precise ways, over long distances. Optical fibers can carry data at a rate of gigabytes per second, or the equivalent of several thousand phone conversations in parallel.		=== Fiber Requirements ===

The extraordinary transparency of optical fibers materials makes it possible to propagate light sometimes hundreds of miles without amplification.
