Then, no significant progress in optical communications, laser optical fibers near the beginning of 1960 and 1970 developed a series of technological advances will not be displayed. Finally, from the light-wave communication system is being fielded in 1978, the practice is allowed in the world.
These systems enable near - infrared, and optical fiber transmission path of the electromagnetic spectrum use. The purpose of this paper are different strategies, delivery methods and measurement methods of optical fiber communication system that can be interpreted. The light in the fiber, designed to link and network, and optical fibers, photonic devices and optical fiber communication system, and the conference proceedings can get more information about the progress of development theory.
