Power management is performed in an optical access network to reduce energy consumption. Service information is determined about traffic at the first node. Power management is controlled based on the determined service information. The first node can control power management at the first node and/or the second node. The first node can categorize traffic according to service and determine traffic activity per service. Service information can include service type of the traffic, traffic class of the traffic, and/or quality of service requirements of the traffic.
