摘要
采用数值分析方法 ,研究了 1 0 Gbit/s光传输系统在前向、后向、对称色散补偿配置下的传输性能 ,分析了不同色散补偿量与 SPM效应对系统传输的影响 .研究结果表明 ,在后向补偿配置下 ,适当的欠补偿优于全补偿与过补偿 ,但在前向与对称补偿配置时 ,近似全补偿情况下系统的补偿性能达到最优 ,并且优于后向补偿方式 .
The performances of 10 Gbit/s optical transmission system in pre,post and symmetric-compensation are investigated with numerical simulation, and the effects of different compensation values and SPM on transmission system are analyzed. The results show that in the case of post-compesation the performance of proper under-compensation is better than that of full-compensation, but the performances of nearly full-compensation in pre- and symmetric-compensation are best and better than that in pre-compensation.
