In order to find out the properties and development of RDFA, the RDFA with Lband and Sband can meet requirements, such as high capacity, wide band, high gain, low noise and so on, and greatly contribute to the development of dense wavelength division multiplexing (DWDM) system by introducing the construction of the RDFA, adopting the theories of energy level and working over three typical doped fiber amplifiers It has broad application prospect in the field of optical communication.
