针对雅砻江流域光纤通信现状,介绍了几种超长距离光纤通信的关键技术,结合当前光纤通信技术对超长距离光纤通信进行理论建模,对模型的参数进行了研究计算。 According to the current status of optical fiber communication in the Yalong River basin, several key technologies of ultra-long-distance optical fiber communication are introduced. Theoretical models of ultra-long-distance optical fiber communication are established based on the current optical fiber communication technology, and the parameters of the model are studied and calculated.
