A method for quantitatively analyzing the survivability of EPON access network is presented. The relationship between the survivability of network and the intensity of network damage is obtained. Meanwhile, the comparison of survivability among three kinds of backup of EPON access network is put forward. The simulation result shows that, when the coverage area is the same, the survivability of EPON with Node-Fiber Backup is better than that with Trunk-Fiber Backup, and when the number and distribution of ONU are the same, the survivability of EPON with Bus-Fiber Backup is better than that with Node-Fiber Backup. The result is useful not only for forecasting and evaluating the survivability of EPON access networks, but also for EPON access networks topology design.
