Abstract :
A novel architecture of hybrid WDM/TDM-PON based on a dual-fiber ring with access-tree topology is proposed. This system can enable the network operator to easily and flexibly reconfigure wavelength resources in the light of dynamical traffic load and bandwidth requirement by using a ROADM based on WB technology at each RN. Simultaneously, this scheme is able to improve reconfiguration of network in response to the failure of some fiber by utilizing a backup feeder-fiber ring and some optical switches.
