Patent number: 11825249Abstract: A method includes determining a first power level by performing a first series of measurements based on a first series of burst transmissions from an optical transmitter of an optical network unit (ONU) in an optical network. Bursts in the first series of burst transmissions include a first modified preamble. A second power level is determined by performing a second series of measurements based on a second series of optical burst transmissions. Bursts in the second series of burst transmissions include a second modified preamble. A first power level (P0) and a second power level (P1) are determined based on the first power level and the second power level and one or more additional parameters associated with transmissions from the optical transmitter are determined based on P0 and P1. Based on the additional parameters, it is determined whether the optical transmitter complies with specifications of the optical network.Type: GrantFiled: November 10, 2022Date of Patent: November 21, 2023Assignee: Verizon Patent and Licensing Inc.Inventors: Denis A.
