海门市有线电视主干光传输网络环路改造

Loop Transformation of Haimen Cable TV Backbone Optical Transmission Network

随着农村有线电视用户数的增长,农村数字电视的整转,对农村有线电视主干光缆网络的运行安全提出了更高的要求。因此如何解决主干光缆网络的备份,成为网络规划工作者的一个课题。海门通过中心机房的环路建设,为主干光缆网络实现了主备线路的自动切换,保证了信号传输的不间断。

Along with the growth of rural cable subscribers,the rural digital TV for rural cable TV turn,the safety operation of the main optical network put forward higher request.Therefore,how to solve the main stem of optical network backup becomes a project for our network planning workers.Through the loop construction center room,Haimen gives priority to stem the main optical network for realization of automatic switching,ensuring line the signal transmission uninterrupted.
