Abstract
In the energy-saving technology of TWDM-PON, in order to avoid the delay deterioration caused by the failure to wake up the ONU receiver in time, the ONU receiver usually needs to remain open, which is bound to cause unnecessary idle energy consumption. For this reason, an energy management mechanism based on pipelined cycle polling (PCP-EMM) is proposed in this paper. Through pipelined cycle polling, ONU can obtain the authorization information of the next polling cycle in advance, so as to solve the problem that ONU cannot be awakened in time because of not knowing the arrival time of burst data in the process of downstream transmission. In addition, the thought of modularization at both ends of ONU and OLT is introduced, according to which each module will be closed or awakened adaptively through the effective management of module energy state, so as to reduce the energy consumption of the network. The simulation result shows when the network load is less than 90%, PCP-EMM can effectively reduce the energy consumption of the system while meeting the delay limitation of the service. And the highest energy-saving rate is up to 53.77%.
