广播电视传输网是传输广播电视节目信号和数据信息的重要基础设施,广播电视节目信号和数据信息安全畅通的传输离不开广播电视网的安全运行,网络能否安全运行又主要取决于日常维护,网络维护看似简单但却事关重大,因而对广播电视网络的维护工作一定要加强,特别是对跨行政区域距离传输的广播电视光缆传输干线网,如跨省辖市的省级广播电视光缆传输干线网和跨省市的国家级广播电视光缆传输干线网的维护工作更要加强,只有加强了广播电视网络的维护才能为在广播电视网上开展其他业务提供有力的保障。
The radio and television transmission network is an important infrastructure for transmitting radio and television program signals and data information. The safe and smooth transmission of radio and television program signals and data information can not be separated from the safe operation of radio and television networks. Whether the network can operate safely or not depends mainly on routine maintenance , Network maintenance may seem simple, but it is of great importance. Therefore, the maintenance of radio and television networks must be strengthened, especially for transmission of radio and television optical fiber cables across administrative areas, such as provincial radio and television stations across provincial cities The maintenance work of optical cable transmission trunk network and national and provincial transmission network of national broadcast and television optical cables must be strengthened. Only by strengthening the maintenance of radio and television networks can we provide effective protection for other businesses on the radio and television network.
