| 摘 要： | 本文主要分析副载波多路复用模拟光传输系统中激光器的非线性畸变，提出一个激光器非线性失真分析的完整的数学模型，特别考虑了多路副载波情况下激光器的削波影响。认真分析了ＱｕｎＳｈｉ等人的论文，对他们提出的传输系统中ＣＳＯ和ＣＴＢ的计算公式进行了改进，考虑了高阶失真项的影响。理论推导已为实验所得多路光纤ＣＡＴＶ链路中的ＣＳＯ和ＣＴＢ结果所证实。

| Abstract: | This paper deals with the analysis of laser nonlinear distortion in subcarrier multiplexing analog lightwave transmission systems.A complete mathematic model for the laser nonlinear distortion analysis is presented which particularly takes into account the laser clipping effect in the multiple subcarriers case.The previous work published by Qun Shi et.al.has been checked and modified to include the contribution of higher order distortion of laser output to CSO and CTB formula of the transmission system.Finally the theoretic results is confirmed by the experiment of CSO and CTB measurements in a multichannel optical fiber CATV link. |
