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 present disclosure extends the flow control in a DSL communication system to include a remote back-pressure flow control within a DSL receiver of the DSL communication system. The remote back-pressure flow control can prevent a DSL transmitter of the DSL communication system from overwhelming the DSL receiver. The remote back-pressure flow control is implemented within a receiving network processor (rx-NP) of the DSL receiver to prevent the DSL transmitter from overwhelming the rx-NP.
