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.

Abstract: A system, method, and computer program product for a flashless optical network unit (ONU) in a Passive Optical Network (PON) are provided herein. The method includes the steps of synchronizing on a downstream signal of an optical line terminal (OLT), receiving a first software from the OLT for its operation on a reserved downstream channel of the OLT, and storing the received first software in a volatile memory. The ONU does not pre-store the first software in a non-volatile memory.

Abstract: The Optical line terminal (OLT) tracks the number of data packets, bandwidth per user, and other data packet statistics. DDR (DRAM) is used to store the information tracked by the OLT. The DDR is accessed in a burst mode. In particular, the data is initially stored in an on-chip cache memory and then the data is sent periodically to the DDR in a burst mode. Leaky buckets can be used for each flow, and time stamps can be used to determine the last time the bucket was accessed.
