Reliability and cost analysis of passive optical networks

In this talk the cost of building resilient passive optical networks (PONs) is analyzed in relation to the connection availability performance. Both standard and several novel PON protection architectures are considered. A new measure for cost efficiency of protection is proposed to compare different protection architectures in order to select the most appropriate ones for particular groups of clients. To evaluate the different PON protection schemes we propose a cost-reliability measure (CRM) in order to capture the trade-off between the deployment cost and reliability performance. The CRM values obtained for each considered protection scheme allow for selecting the most cost-efficient protection for PON customers.
