摘　　要：针对单信道SDH光接口参数在评判DWDM系统色散补偿方案中应用的问题进行了研究,首先给出了SDH光接口及其参数的类型,分析了光波分复用系统中色散问题的复杂性,然后给出了STM-16光接收机参数,引出了最小灵敏度这一参数,提出用单信道SDH光接收机参数评判色散补偿方案的可行性,最后结合误码率测量,给出了最小灵敏度参数的测量方法。在实际的光纤复用系统中,使用某一色散补偿方案,测量出最小灵敏度,就可得到这一色散补偿方案性能的优劣的结论。A probe has been done into the applications of SDH optical interface parameters in evaluation of dispersion compensation proposals of DWDM systems. Firstly, SDH optical interface and parameters were introduced, and complication of dispersion problem in optical wave division multiplexing systems was analyzed. Then, STM -16 optical receiver parameters were given, by which minimal sensitivity was introduced, and the feasibility of evaluation of dispersion compensation proposals using single - channel SDH optical receiver parameters was proposed. Finally, measuring method of minimal sensitivity was proposed, it combined with bit error rate measuring. In practical fiber multiplexing systems, with a certain proposal of dispersion compensation, the property of this proposal can be evaluated by measuring out the minimal sensitivity.
