| 摘 要： | 本文讨论了光纤色散对ＩＭ／ＤＤ光纤通信系统再生中继距离的限制，导出了适用于各种眼图恶化量、归一化脉宽和光源线宽展宽因子，且便于工程计算的Ｂ２Ｌ表达式。通过与其它理论的比较、计算机仿真研究和对实际系统实验数据的分析，说明了该公式所得结论的正确性以及其它结果的限制条件。

| Abstract: | The dispersion limitation on the regeneration spacing of IM/DD fiber transmission systems is studied in this paper. A formula of B2L for arbitrary eye opening penalty, normalized pulse width and source linewidth enhancement factor is derived. Results from our formula and computer simulation are compared with published data in the literature, which shows the correctness of our theory as well as the constraints of other results. |
