The invention especially relates to a wireless optical broadband access network optimization deployment method based on survivability rerouting, and belongs to the technical field of communication networks. The wireless optical broadband access network optimization deployment method SRRD based on survivability rerouting is used for achieving the purpose of the optimized layout of wireless routers. The method includes the following steps that firstly, a whole network region is divided into M*M grid cells, and the center of each grid cell serves as a possible position for containing one wireless router; secondly, Rx is set for representing the wireless routers currently to be placed, under the conditions that k node-disjoint paths and wireless access hop count constraints exist from each ONU to another ONU, all the candidate positions capable of containing the wireless routers Rx are calculated.
