Abstract: A theoretical analysis of erbium-doped fluoride fiber amplifiers(EDFFAs) is presented in this paper. By using this theoretical modelling its gain, noise and saturated output power performance have been calculated numerically, and compared with erbium-doped silica fiber amplifier(EDSFA).

Key words: optical fiber communication, erbium-doped fiber amplifier(EDFA), wavelength division multiplexing(WDM)
