电视信号在省网内的传输与维护

The Transmission and Maintenance of the Television Signal in the Province Network

DWDM技术允许各载波信道在一条光纤内同时传输,充分利用光纤的带宽,可直接接入多种业务,基于DWDM的SDH传输平台已成为骨干传输的主流,在此平台上,一部分带宽用来传输广播电视节目,另一部分用来直接传输用户数据等,介绍广播电视信号在省网传输中的常见故障及解决办法。

The DWDM technology allows various carrier current channel to transmit in an optical fiber, fully has used the optical fiber bandwidth, may directly turn on the many kinds of services, transmits the platform based on DWDM SDH to become the backbone transmission the mainstream. In this platform, part of band widths use for to transmit the broadcast television program, another part uses for the direct transmission user data and so on. This paper introduces the fault in the transmission of television signal in the province network and solutions.
