Optimal techno-economic selection of optical access network topologies involves finding the key techno-economic criteria that will be used for the topology selection. We have developed an analytical method for calculating optimal techno-economic selection of topologies. The proposed method determines the required number of optical fibers of certain characteristic segments of the access network, taking into account the density of users per 1 km2, guaranteed bandwidth for each user, and the possible topology of optical access networks. The results show that the increase in density of users, with a constant guaranteed bandwidth, isn't the determining factor for the optimal choice of topology. On the other hand, the same results show that increasing the guaranteed bandwidth, with a constant density of users, represent critical elimination factor for optimal techno-economic selection of topologies. Under the same conditions, results show that the initially favorable topology, in terms of techno-economic feasibility, after a few iterations in bandwidth increase may become unfavorable compared to competing considered topologies.
