摘　　要：现有光网络工程主要采用OSNR指标对系统性能进行衡量或评估,分析了OSNR指标主要存在的问题,通过研究非线性效应及其影响,指出开放海缆标准的GSNR指标目前难以适用于陆地骨干系统。最后建议骨干光网络工程设计及验收阶段增加光通道代价指标,并给出了实施建议。Existing optical network projects mainly use OSNR to measure or evaluate system performance. It analyzes the main problems of the OSNR,and points out that the GSNR of the open submarine cable standard is currently difficult to apply to terrestrial backbone systems by studying the nonlinear effect and its impact. Finally,it is recommended to add the OSNR penalty index in the backbone optical network engineering design and acceptance stage,and the implementation suggestions are given.
