Abstract
Hybrid WDM/TDM-PON as a key solution is a smooth evolution of the passive optical network to Next-Generation Passive Optical Networks (NG-PON). In order to combine the capacity of metro and access networks, it is desirable to propose the Long-Reach (LR) PON, and the propagation delay is proved to be the obstacle during the upstream resource allocation, so we propose an efficient DWPBA for the Long-Reach hybrid WDM/TDM-PON by separating the data messages and REPORT messages under multi-thread scheduling, which achieve high channel utilization and low packet delay when fiber length increased to 100 km.
