Although Erbium-doped fiber amplifier is still the mainstream of optical fiber communication nowadays, it has some limitations. The operation of EDFA is limited to 1530-1610nm, so it is an important research direction to explore different elements. This paper introduces three kinds of fiber amplifiers doped with different rare earth elements: Thulium-doped, YttErbium-doped, and Bismuth-doped fiber amplifiers. The optimal optimization performance is obtained through comparison logic by adjusting various parameters. The maximum gains of three rare-earth-doped fiber amplifiers in different wavelength ranges are obtained: The maximum gain of a Thulium-doped fiber amplifier is 51dB in the wavelength range of 1900nm to 2050nm. The maximum gain of a YttErbium-doped fiber amplifier is 62. 5dB in the wavelength range of 1020nm to 1080nm. The maximum gain of a Bismuth-doped fiber amplifier is 23dB in the wavelength range of 1640nm to 1770nm. These works pave the way for future research.
