Abstract

PON-based access networks envisage the demonstration of scalability to allow gradual deployment of time and wavelength multiplexed architectures in a single-platform without changes in fibre infrastructure and also highly-efficient bandwidth allocation for service provision and upgrade on-demand. This is achieved by the application of coarse-fine grooming to route reflective-ONUs of time and wavelength PONs collectively and the development of MAC protocols enabling the OLT to dynamically assign available time slots among ONUs and demonstrate efficient bandwidth and wavelength assignment.
