低频调制EoC信号在有线电视网络中衰减值分析

he Attenuation Value Analysis of Low-Frequency Modulation EoC Signal on CATV Network

通过对东港开发区有线电视网络组网结构的介绍,分析网络中分支分配器件、双向辅助器件和同轴电缆对低频调制EoC信号的损耗,得出低频调制EoC信号在东港开发区有线电视网络中的衰减值满足要求的结论。

Through the introduction of the CATV network structure of the Donggang development zone, this pa- per analyze the loss of low - frequency modulation EoC Signal affect by the branch distributor, the two - way auxiliary device and the coaxial cable. At last, the paper reaches the following conclusion： The Attenuation Value of low - frequency modulation EoC Signal at the CATV network of the Donggang development zone can meet our requirements.
