摘要
随着数字电视的革新、城市和新农村的迅速发展,施工建设导致数字电视光网络出现严重的断网现象,而通过前端机房主备信号源建设及汇聚机房、接入机房的环网建设,能更好地解决这一问题。主要介绍了通过三级机房的设备搭建,实现了信号中断的减少和用户体验感的提高。
With the innovation of digital television and the rapid development of cities and new rural areas, the construction of the DTV optical network severely disrupted the network. The problem can be well solved through the construction of the main backup signal source and the ring network connecting the convergence ma- chine room and the access machine room. The article mainly introduces the equipment construction of the three-level machine rooms, to realize the decrease of signal interruption and the improvement of user experience.
