what is long haul fiber
long-haul optics. Long-haul optics refers to the transmission of visible light signals over optical fiber cable for great distances, especially without or with minimal use of repeaters. Normally, repeaters are necessary at intervals in a length of fiber optic cable to keep the signal quality from deteriorating to the point of non-usability. In long-haul optical systems, the goal is to minimize the number of repeaters per unit distance, and ideally, to render repeaters unnecessary.
An optical fiber is a thin fiber of glass or plastic that can carry light from one end to the other.The study of optical fibers is called fiber optics, which is part of applied science and engineering.Optical fibers are mainly used in telecommunications, but they are also used for lighting, sensors, toys, and special cameras for seeing inside small spaces.he study of optical fibers is called fiber optics, which is part of applied science and engineering.
