Suboptimal PON network designing algorithm for minimizing deployment cost of optical fiber cables

In order to meet the bandwidth requirements for the access network, many network operators nowadays have been rapidly expanding their fiber-to-the-home (FTTH) service area. In such an area, a passive double star (PDS) network, which shares one optical fiber with multiple subscribers by using a power splitter, is commonly deployed as an infrastructure for the passive optical network (PON) systems. One of the main focuses for PON network planning is to determine the locations of the optical splitters and optical fiber cable routes that connect every splitter to the central offices (COs) based on the forecasted demands, within a limited deployment cost under realistic restrictions. In this paper, we propose and demonstrate a novel suboptimal design algorithm of PON optical distribution network (ODN). Based on the forecasted demand, it can automatically generate a suboptimal PON network in terms of the total cable deployment construction length under realistic restrictions.
