摘要：Disclosed herein is an optical fiber comprising a plurality of dopant

concentration profiles in a core of the optical fiber; where the first dopant concentration

and the second dopant concentration are each varied in a stepwise manner and wherein aratio of the first dopant concentration to the second dopant concentration is operativeto result in an interaction of a fundamental optical mode at a given wavelength with aplurality of acoustic modes thereby increasing a ratio of Brillouin Scattering intensityratio of secondary, tertiary or quarternary peak relative to a Brillouin Scattering intensityof a primary peak to be greater than 0.4 in a Brillouin Scattering spectrum.
