Results from EU FP7 Project OASE on Next-Generation Optical Access

Over the last three years, a comprehensive techno-economic analysis of Next-Generation Optical Access (NGOA) has been performed in the EU FP7 project OASE (Optical Access Seamless Evolution). Several types of Passive as well as Active Optical Networks (PON/AON) have been investigated, with regard to system, cabling and fiber cost, and Operational Expenditures (OpEx) including operations, maintenance, and energy-consumption cost. The analysis was performed for several degrees of active-site consolidation as well as for several sustainable per-client bit rates. Here, the analysis of the relevant PON approaches is presented with focus on system and infrastructure costs. With increasing site-consolidation degree and per-client bit rate, the optimum solution shifts from G-PON / XG-PON1 towards WDM-based PON solutions.
