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: Systems and methods are provided for generating an accurate, stable measurement for a laser bias current. The average current and the extinction ratio are controlled using a dual control loop. The transfer function between the laser and a monitor photo diode (MPD) is characterized. A laser driver control module predicts the average power that will be measured using the MPD relative to the data being transmitted, and this information is used to control a laser driver.
