摘要
我国早期的长途干线光缆基本建成于20世纪末,至今已有二十多年,无论是光缆容量还是使用寿命,均已开始进入更新替换的升级周期。下一代长途干线光缆网的构建,可充分利用高速公路管道资源丰富、路径短的优势,借助高速公路管道路由建设光缆。
China’s early long-distance trunk optical cables were basically completed at the end of the 20 th century.It has been more than 20 years.Both the optical cable capacity and service life have begun to enter the upgrading cycle of renewal and replacement.The construction of the next generation long-distance trunk optical cable network can make full use of the advantages of rich highway pipeline resources and short path,and build optical cables with the help of highway pipeline routing.
