One of the first transmission link known to the eyes is a fire-signal used by people from other nations in the eighth century BC by sending an alarm, calling for help, or advertising of certain events. Improved distribution system is not pursuing the eye they are very effective due to limited technology at that time. For example, the transmission of information via the communication link is very limited because the infection rate depends on how fast the sender can move the hands, eyes and receiver of the phone signals the human eye, line-of-sight transmission path is required, and atmospheric effects like fog and rain to ensure infection. So, he turned quickly, more efficient, more reliable and send messages via couriers on the road network.
Finally, no significant developments in optical communications was found for the discovery of lasers in the early 1960s and a series of technology development related to the eyes of almost 1.970 degrees. This event will eventually be allowed to conduct communication system of light waves will begin to decrease around the world in 1978.
This system works at near-infrared region of the electromagnetic spectrum and using the fiber as a combination of HIV. The purpose of this book is to explain the various technologies, implementation strategies, and performance testing methods to create a system that makes possible the optical fiber communication. Readers may obtain additional information about the theory of light propagation in fibers, the pattern of links and networks, and reform of fiber optics, photonic devices, and optical fiber communication systems, and conference proceedings.
