| Abstract: | At first, the paper briefly describes the principle of centralized power supply on the HFC system, and then analyzes the reasons for the centralized power supply failures from practice to theory base on the network power supply failure phenomenon, further validation the stability effect from coaxial cable and connectors. With the purpose to provide a reference to the rdated maintenance work, a number of common factors which probable lead to such failures and the corresponding treatment methods have summarized at last. |
