According to the planning problem of multi- layer level and multi node passive optical network (PON) in distribution power supply optical communication network, multi-layer level cycle inheritance stacked genetic algorithm based on basic genetic algorithm is proposed for the first time. The outer layer distribution optical network is used to inherit inner layer network gene to choose adaptation function in the layer network. The layer lev-el optical distribution optimization problem of multi-layer level PON is resolved by the algorithm. Simulation results show that the algorithm is feasible and the topology optimization of four-layer level network with star structure is realized. The optimized network obtains the best star structure network topology and the communication construction cost is reduced.
