摘　　要：针对强度调制-直接检测光正交频分复用无源光网络(I M-DDO OFDM-PON)中受激布里渊散射(SBS)带来的干扰,提出并分析了两种抑制SBS方案的原理和可行性,即相位调制方案和梳状谱发生器方案,通过一系列仿真验证对比了两种方案在I M-DDO OFDM-PON中对SBS的抑制效果和对系统性能的改善。Focuses on the interference introduced by stimulated Brillouin scattering（SBS） in intensity modu- lation-direct detection optical （IM-DDO） OFDM-PON systems, this paper proposes and analyzes the theory principle and feasibility of two schemes in order to suppress SBS, corresponding to phase modulation scheme and comb spectrum generator scheme respectively, and then compares the effects in suppression of SBS and improves on system performance in IM-DDO OFDM-PON of the two schemes through a series of simulation.
