【 摘 要 】

We propose a novel method to measure the nonlinear parameter of an optical fiber by characterizing the evolution of self-phase modulation (SPM) based on Brillouin optical time-domain analysis (BOTDA). The nonlinear parameter of an optical fiber is measured to be 2.03 W-1km-1, which agrees well with previously reported result.
