This paper presents a planning analysis of FTTH access network with and without redundancy. Traditionally, access networks are planned only without redundancy, which is mainly due to lowering the cost of deployment. As fiber optics provide a huge amount of capacity, more and more services are being offered on a single fiber connection. Therefore, as a single point of failure in fiber connection can cause multiple service deprivation, redundancy is very crucial. In this work, an automated planning model was used to test different scenarios of implementation. Cost estimation is presented in terms of digging and amount of fiber used. Three topologies, including the traditional one ”tree topology”, were tested with a combination of various passive optical technologies.
