WDM/OTN系统OSNR的计算与优化

摘要

It first simplifies the calculation formula of OSNR of concatenated EDFA in WDM/OTN system and gives the simple and accu-rate calculation approach, and presents the specific optimization measures. It also verifies the measures in combination with the example of local OTN of Songyuan city in Jilin Mobile.%　　在对级连EDFA的OTN/WDM系统的OSNR计算公式进行简化的基础上，提出了简单准确的计算办法，根据简化结果提出了一些具体优化措施，并以吉林移动松原市本地OTN为例进行了验证。
