Optical Fiber Amplifier (OFA) is a new type of all optical amplifier used in fiber optic communication lines to achieve signal amplification. Belongs to sensor type components. According to its position and function in fiber optic circuits, it is generally divided into three types: relay amplification, preamplification, and power amplification. Compared with the traditional semiconductor laser amplifier (SOA), OFA does not need to go through complicated processes such as photoelectric conversion, electro-optic conversion and signal regeneration. It can directly carry out all-optical amplification of the signal, which has good "transparency", and is especially suitable for the relay amplification of long-distance optical communication. It can be said that OFA has laid a technological foundation for achieving all optical communication
