This paper discusses a power save management method appropriate for the features of the fiber-optic access network based on Passive Double Star (PDS) topology, where PDS termination processing LSIs for the Optical Network Unit (ONU) operate intermittently and the usage rate is low at the residential customer. We developed PDS termination processing LSIs for the ONU, performed power management, and evaluated the degree of consumed power.
