PON network designing algorithm for suboptimal deployment of optical fiber cables

A passive double star (PDS) network, which shares one optical fiber with multiple subscribers by using a power splitter, is being deployed as an infrastructure for the passive optical network (PON) systems. One of the main focuses for PON network planning is to determine the optical cable route of a point-to-multipoint network that connects every subscriber to the central offices (COs) through the power splitter(s) within a limited deployment cost under realistic restrictions, such as possible fiber paths, the splitting ratio of optical splitters and locations, when the locations of COs and subscribers are given. In this paper, we propose a novel suboptimal design algorithm for PON outside plant deployment. Under the realistic restrictions, the algorithm can automatically generate a suboptimal PON network that connects every subscriber to the COs in terms of total fiber length.
