The key question for the next ~5 years is how to cost-effectively extend the capabilities of existing and recently planned optical access networks. From many operators, the wish-list for next-generation optical access (NG-OA) systems includes
• Longer reach than the one possible with GPON (~20 km) due to network (central office) consolidation, preferably up to 60 or even 100 km,
• Large number of subscribers per fibre connected to the central office (i.e., more than the 32-128 subscribers possible with GPON today), preferably >1000 (the project goal),
• 1 Gb/s per subscriber or more,
• So-called colour-less ONT, i.e. only one type of ONT is required in WDM-PON.
Main WP4 objectives are:
• Comprehensive survey of suitable NG-PON system concepts, which will result in a Technology Roadmap.
• Assessment and comparison of the system concepts with respect to technical requirements (from WP2 and WP4), space and power consumption, cost, etc.
• Understanding of the operations aspects of the candidate systems, such as installation, configuration, maintenance, fault management and resilience, performance monitoring, etc.
• Selection of candidate system concepts to be further investigated
