Abstract
Topologies for economically bringing fiber to the home are under investigation. This paper examines the outside plant (OSP) costs of five different fiber to the home topologies and compares them to the cost of existing copper topology for the delivery of telephone service to the home. The costs were analyzed for a newly built subdivision. The topologies include, two fiber star, one fiber star, splitter-star, active pedestal, and bus. The costs examined are for fiber optic cable, hardware, and interconnect devices. Topology costs are calculated from current and projected prices for fiber optic components. The calculations for each topology include the components from the connector in the Central Office (CO) or Remote Terminal (RT) to the connector at the home or pedestal for the fiber system. The component parts include terminating equipment inside the CO or RT, feeder, distribution, and drop cables, splices, connectors, cross connect, taper hardware, and pedestals. Electronics (opto-electric conversion at CO/RT and pedestal/home) costs and installation costs are not included in the analysis. Addition of electronics and installation costs for each topology will allow telco planners to determine the overall topology cost. The analysis reveals the active pedestal and bus topologies as the most efficient deployment of OSP equipment and suitable economic candidates for fiber to the home systems in the near term. Splitter based systems become viable later on and one fiber systems are possible if additional revenue is available.
