摘要
受激布里渊散射(SBS)的抑制是光纤AM-CATV外调制传输系统中关键技术之一。理论分析了双(多)频率相位调制抑制SBS的方法,较之传统的单频率相位调制法,双(多)频率相位调制对SBS阈值有较大提高,并对双频率相位调制法中调制频率的选择进行了分析与计算。
Abstract
Stimulated Brillouin Scattering (SBS) suppression is one of the key technology in optical fiber AM-CATV externally modulated transmission system. In this paper, a novel two signal phase modulation for SBS suppression is presented. The theoretical analysis and calculation have shown that the two signal phase modulation is more efficient than the single signal phase modulation for the increase of SBS threshold. The choice of frequency in two signal phase modulation is also analyzed and calculated in this paper.
