Design of ADSL as the backup transmission line of the new generation weather radar

汕头雷达站新一代天气雷达投入业务试运行后,采用2 M带宽的光纤线路作为主要的通信手段,同时采用2 M带宽的ADSL作为备份的通信线路,当光纤线路出现中断时,立即起用ADSL备用线路,确保雷达气象产品、图像、资料等能及时传输到中国局、省局和汕头市局。

After the new generation weather radar was put into business trial operation in Shantou radar station,the main communication means is the optical fiber line of 2M bandwidth and the backup means is ADSL of 2M bandwidth.When the interruption of the optical fiber line occuring,the standby line ADSL can be used immediately to make sure radar meteorological product,images,information and so on.It can be transmitted to China station,Guangdong station and Shantou station.
