摘要：Optical fiber communication is the best transmitting data may be capable of Terabit per second data rate. No existing single communication system can make complete use of this speed. Many types of Optical amplifiers have been developed to amplify optical signal. EDFA is one of the examples of optical fiber amplifier to amplify optical signal. To design optical amplifier gain and NF are most significant points. Gain and NF are more significant points. Gain and NF have very strong impact on EDFA configurations. This paper focused on four important sections. First section is EDFA have enabled to use WDM, DWDM Technique, which uses denser channel spacing in order to achieve higher bit rates. The second section is based on the theoretical background of EDFA analysis and the parameters used for amplification related to spontaneous and stimulated emission. The third section is configuration of EDFA from the single pass to the quadruple pass. The fourth section is the different methods used for gain flattening of EDFAs depends on a large number of device parameters such as erbium ion concentration, amplifier length, pump power and core radious
