Abstract

Abstract : This study provides an insight into the effectiveness of an optical network unit (ONU) sleep technique, where a subcomponent of the ONU is powered down during the absence of input traffic. The approach contributes to the realisation of advanced power efficiency over a wide range of input throughputs in situations where downstream traffic exceeds upstream traffic in recent residential networks. A numerical simulation showed that power‐saving effectiveness could be achieved for an Mbit/s downstream throughput without latency implications in the Tx sleep mode.
