%X Because of the adulteration or the existence of asymmetric stress in fiber,Brillouin back scattered-light detected by the equipments was presented as multi-peaks.Thus,a new way to simulate the data of Brillouin back scattered-light power spectrum which is based on a method of area-dividing and the least squares nonlinear regression analysis was proposed.It can not only be used to simulate the single-peak Brillouin back scattered-light power spectrum,but also to identify and process data of multi-peak spectr...
