小区有线电视双向网设计实践

Design of the Plot CATV Two-way Transmission Network

在双向HFC网络中，为保证传输通道的性能指标，除了选用高屏蔽性能的网络器材外，网络的系统设计及回传系统的调试也很重要，故以一个小区的有线电视双向网设计作为典型加以介绍。

In the bidirectional HFC network, he high-performance shielding network equipment is adopted to make sure the performance index of the transmission channels, while the design of the network system and the debugging of the feedback system are also very important. So this article introduces a plot cable TV two-way transmission network design as an example.
