Dimensioning and Assessment of Protected Converged Optical Access Networks

Optical access networks are continuously evolving towards next generation solutions offering much higher bandwidth per end point and considerably longer optical reach. Their dimensioning and planning should be accurate and as close to realistic values as possible to become useful to network operators. This work presents a Converged Access Network Planning and Dimensioning Tool for planning and dimensioning of networks for Fixed Mobile Convergence based on Geographical Information Systems (GIS). These networks connect to the Central Office (CO), end points requiring different capacity and reliability constraints. This tool proposes a new clustering algorithm to decrease fiber and duct length. Furthermore, five protection schemes have been proposed, modelled and compared in Dense Urban, Urban and Rural areas to improve connection availability to the more availability demanding end points. The proposed assessment methodology compares the following parameters: component cost, power consumption, connection availability, indirect improvement in connection availability of residential users, Failure Impact Factor (FIF) and protection fiber length required per Macro Base Station (MBS). The paper also includes a consolidated comparative analysis to find the best solution fulfilling specific requirements of any network/ service provider.     «
