Abstract :
We propose a novel hybrid wavelength-division-multiplexed (WDM)/ time-division-multiplexed (TDM) passive optical network (PON) architecture for next-generation optical access networks. This PON is based on a novel virtual PON (VPON) mechanism that will allow wavelength channels to be flexibly allocated to specific ONUs in a dynamic fashion. Dynamic wavelength allocation (DWA) algorithms and dynamic bandwidth allocation (DBA) algorithms can be combined to optimize the use of bandwidth resources in such a wavelength-agile hybrid WDM/TDM network. We experimentally demonstrate the proposed architecture using a 10-Gb/s downlink and 1.25-Gb/s uplink transmission setup. The experiment results show that the proposed scheme has good transmission performances with dynamic ONU re-grouping functionality.
