Bentahar Attaouia, Kandouci Malika, Christelle Aupetit-. Berthelemot . Evaluation of Gain and Quality Factor of an Erbium Doped Fiber Post-, Pre- and in-line Amplifier for GPON. International Journal of Computer Applications. 94, 6 ( May 2014), 40-45. DOI=10.5120/16350-5681
Erbium Doped Fiber Amplifiers (EDFA) have become more popular in optical networks. The concept of extending the reach to 60 km of GPON with a 1:64 split ratio through the introduction of amplification (EDFA) designed for 1550 nm in downstream is presented with simulation of GPON Optical Network in terms of different parameter (fiber length , signal input power , number of users, splitter loss…). Moreover in this paper, was study different characterizations of EDFA amplifier, which depend essentially on the opt-geometric parameters, such as concentrations of ions erbium, length of the erbium doped and core radium fiber and the effect of those parameters to optimize the gain G and quality factor Q for different amplifier ( post-, pre- and line amplification) configurations in GPON system.
