Exploiting state of the art WDM-PON technologies for building efficient FTTC networks

In this paper, we evaluate the performance gains of a novel hybrid 2-stage TDM/WDM PON access network over state-of-the-art Long-Reach WDM PONs. The proposed network architecture exploits very low cost end-user ONUs and achieves energy efficiency, reduced complexity and high-level scalability. The scheme allows a group of users to share an ultra-wide band long reach WDM-PON, in a fiber to the cabinet configuration, leading to core node consolidation and access-core integration. We quantify the benefits evaluating its application in large metropolitan area configurations using network planning techniques to reduce the number of nodes that are required to serve the expected capacity demand.
