Business models and their costs for next generation access optical networks

Optical access networks are the best networks to offer high bandwidth required by future applications. However, the full deployment of optical fiber to the final user involves high road and building works and costs, which seem only affordable in highly dense areas. Therefore, a good analysis of costs for different scenarios is required. The FP7-project Optical Access Seamless Evolution (OASE) studies different scenarios consisting of network architecture (WDM PON, Hybrid WDM/TDM PON, Two-stage WDM PON, NG-AON), population density (dense urban / urban / rural) and node consolidation schemes with their specific cost characteristics. Revenues are calculated by adding demand uptake (low/average/high) to the scenarios. Finally, costs and revenues are benchmarked for the different actors involved (passive infrastructure providers, network providers, service providers).
