摘要

对外调制光波远距离AM-CATV系统中的受激布里渊散射进行了分析。受激布里渊散射阈值功率(P/sub SBS//spl ap/7 dBm)是影响传输距离的主要因素。比较了两种提高SBS阈值的方法:已知的抖动法和一种新的初始脉冲调制法。

New method of SBS counteracting in long distance analog CATV link

Analysis of stimulated Brillouin scattering (SBS) in externally modulated lightwave long distance AM-CATV systems is presented. The stimulated Brillouin scattering threshold power (P/sub SBS//spl ap/7 dBm) is the main limiting factor of transmission distance. Two methods of increasing the SBS threshold are compared: well known dithering method and new one, called initial pulse modulation method.
