Two experimental configurations are investigated and compared. One is to make the pulse propagate in a region slightly detuned from a gain peak where the group velocity change is negative and the other is to make use of the large anomalous dispersion appearing between two gain peaks. We experimentally show that the second method produces pulse advancement with lower distortion than the first one.Optical fibersBrillouin scatteringDispersion (waves)Electric distortionGain-assisted pulse advancementStimulated Brillouin scatteringAnomalous dispersiontext::journal::journal article::research article
