摘　　要：在光波分复用系统从100 Gbit/s单波速率向200 Gbit/s及更高速率过渡之际,提出基于OSNR进行传输系统通道代价计算的参考模型,针对模型涉及的线性噪声影响、非线性噪声影响和通道光谱响应均衡影响进行了全面解析和量化研究,明确了各影响因素的计算表达方式。并综合解析、量化和计算表达,给出了传输系统性能及通道代价的计算模型,为系统性能仿真及工程精准预测提供了坚实的理论支撑。As the WDM system transits from 100 Gbit/s single wave rate to 200 Gbit/s and higher,a reference model for channel cost calculation of transmission system based on OSNR is proposed.The effects of linear noise,non-linear noise and channel spectral response equalization involved in the model are comprehensively analyzed and quantified,and the expression of each factor is clarified.The calculation model of transmission system performance and channel cost is given by comprehensive analysis,quantification and calculation expression,which provides a solid theoretical support for system performance simulation and engineering accuracy prediction.
