Abstract	Survivability is one of the key issues in Fiber-Wireless (FiWi) broadband access network since huge data loss could be caused by single segment failure. Previous schemes focus on protecting FiWi against single segment failure by deploying backup fibers. However, these schemes suffer from two key problems. First, they ignore optimizing the selection of backup ONUs, which determines the recovery delay of the traffic interrupted by failure. Second, they underutilize the residual capacity of segments, thus require high cost of backup fibers. In this paper, aiming to tackle the inefficiency of previous schemes, we propose an efficient protection scheme, called Optimizing Backup ONUs selection and backup Fibers deployment (OBOF), to enhance the survivability of FiWi against single segment failure. Extensive experimental results demonstrate that our OBOF scheme outperforms the previous schemes significantly, especially in the scenario of higher traffic demand.
