Appropriate network architectures are essential in order to take advantage of the high bandwidth and long-reach capabilities that next-generation optical access (NG-OA) technologies can offer. The massive deployment that we are witnessing today gives great business opportunities for equipment vendors, and network and service providers alike. However, any successful solution will have to meet a variety of technological, economic, environmental, and business criteria.
Extending the reach of access networks from a few kilometres to about 100 kilometres effectively merges backhaul and access networks into a single transport solution. This enables large population coverage with tens of thousands of users per fibre and therefore has the potential to offer significant capital and operational savings. The architectures studied in the framework of WP3 will consider solutions that support site reduction by the choice of an appropriate topology, location and type of passive/active components, and other factors. After reviewing the existing fibre access network solutions, WP3 will propose novel architectures and solutions in accordance with the requirements identified in WP2.
Main WP3 objectives can be summarized as follows:
• To define the boundaries of NG-OA network domains
• To review existing optical access architectures and study both, passive and active concepts
• To propose novel optical access network architectures according to the requirements provided by WP2 which support open access scenarios and site reduction
• To evaluate the proposed network architectures in respect to complexity, scalability, reliability, energy and cost efficiency, and resource allocation
• To study migration paths from the existing infrastructures to the NG-OA networks
