Total cost comparison of Next Generation Optical Access Networks with node consolidation

Next Generation Optical Access Networks (NGOA) are being evaluated based on their maximum reach, the offered bandwidth per user, their client count and their cost. A complete cost assessment of these architectures should take into account not only the required equipment and infrastructure, but also the continuous cost of fault management, service provisioning, network maintenance, power, etc. This paper presents the models used for the cost assessment. Furthermore, a complete cost assessment of four NGOA architectures at three different types of areas for two different node consolidation degrees is given.
