Performance of EDFA Amplifier Position (Pre-, Post- and In-Line Amplification) for Reach Extendibility of GPON-FTTH
Performance of EDFA Amplifier Position (Pre-, Post- and In-Line Amplification) for Reach Extendibility of GPON-FTTH
This article is dealing with simulation of deployment of EDFA optical amplifier in different positions (post- amplifier or booster, in line and pre-amplifier) used for GPON downstream, which depend essentially on the opt-geometric parameters (ions erbium density and length of the fiber doped erbium) and the effect of those parameters to optimize the performance for extending the reach up to 60 km of and with 1:128 split ratio of the GPON. The performance of this system has been evaluated in terms of the quality factor, eye diagram and the minimum of BER with various simulations by sweeping fiber length and input signal power. It has been found that, the pre-amplification was performed and found to be superior with good results to inline and post amplificationn methods.
