Provided by: International Journal of Communication Networks and Information Security Topic: Networking Format: PDF
In this paper, the authors investigate effects of Amplified Spontaneous Emission noise (ASE), Noise Figure (NF) and dispersion chromatic on the performance of DWDM networks using Distributed optical fiber Raman Amplifiers (DRAs) in two different pump configurations, i.e., forward and backward pumping. They found that the pumping configurations, ASE noise, and dispersion play an important role in network performance improving since it reduces noise figure and Bit Error Rate (BER) of the system. Simulation results show that the lowest bit error rate and noise figure when using forward pumping configuration. Moreover, they have also compared ASE noise powers of the simulation with these of the experiment, they are match.
