Abstract
Systems and methods are provided to efficiently manage power in a laser a driver of an optical network unit (ONU) of a passive optical network (PON). Using information from an allocation map, the expected next allocated schedule for a transmission can be determined. The driver can be efficiently powered down and powered up based on the time remaining between the end of the current burst and the beginning of the next expected burst so that power is not wasted while the laser has no data to transmit.
