| Abstract: | Firstly, several current network topology configurations for EPON are presented. By discussing the connectivity and centrality of the network, the reliability of network topology configurations is studied. In view of the advantages and disadvantages of the old configurations, an improved topology configuration, which is suitable to optical fiber subscriber access network, is proposed. |
