摘　　要：利用速率方程 ,探讨了预失真技术对光 CATV系统中激光器非线性失真补偿的可行性 ,设计了预失真电路的结构及参数 ,实验证明了通过合理的设计 ,可使光源的 CSO和The compensation for the nonlinearity of a laser diode in lightwave CATV systems with predistortion techniques is researched both theoretically and experimentally.The designed predistortion circuit shows good compensating effect at high frequency band,which makes the CSO and CTB of the optical transmitter,assessing the multichannel transmission quality,satisfies CATV standard in whole channels.

关 键 词：光CATV 光源 非线性失真补偿
