提出并论证了一种结合打盹和睡眠模式的集中光源WDM-PON的高效节能方案。该方案基于简单的功率检测和本地传输请求。设计了两个逻辑控制单元来切换OLT中各个ONU及其关联收发器的操作模式。采用10Gbit/S下行传输和1.25Gbit/S上行传输实验验证了方案的可行性。仿真结果表明，在线状态下ONU的节能主要来自打盹模式，而不是睡眠模式，而OLT中相关收发器的节能主要来自于ONU处于离线状态的情况。
We propose and demonstrate an efficient energy-saving scheme incorporating dozing and sleep modes for WDM-PONs with centralized light sources (CLS). The novel scheme is based on simple power detection and local transmission request. Two logic control units are designed to switch the operation modes of the respective ONUs and their associated transceivers in the OLT. The scheme feasibility is experimentally verified with 10 Gbit/s downstream and 1.25 Gbit/s upstream transmissions. The simulation results reveal that the energy-saving of the ONUs in the online state mainly arises from the dozing mode, not from the sleep mode, while the energy-saving of the associated transceivers in the OLT is contributed mainly from the situation where ONUs are in the offline state.
