In fibre‐wireless (FiWi) access networks, the achievement of survivability becomes critical because any failure of FiWi components may result in severe traffic interruptions. In this study, the authors proposed a new backup fibre deployment mechanism with the consideration of time‐varying daily traffic demand. Firstly, a new remote node structure for the protection of switching is established to help the backup fibre deployment. Secondly, they formed a minimum deployment cost problem in terms of the daily traffic demand and interrupted traffic protection. Furthermore, a two‐stage algorithm is proposed to solve this problem and obtain an optimal deployment pattern. Simulation results demonstrate that the proposed mechanism can reduce the cost of the backup fibre deployment and the delay of the interrupted traffic recovery significantly.
