Passive optical networks are a popular type of next generation access network which offer significant benefits over legacy copper access networks. In a standard passive optical network, all of the optical network units are constantly powered on waiting to receive packets. However, only one optical network unit can receive packets at a time, so the optical network units spend most of their time idle even when the network is under load. An extension to the cyclic sleep algorithm for high-utilization scenarios is proposed which places optical network units in sleep mode during long periods of inactivity which commonly occur while the other optical network units are receiving packets. The efficacy of this approach is evaluated using a discrete events simulator and validated using an analytical model. A reduction in system power consumption of up to 47.68% is shown to be achievable depending on the distribution of the traffic between the optical network units. Our approach is compared to the existing approach of cyclic sleep and is shown to out-perform it under congested network conditions.
