| Abstract: | 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. |
