ALEXANDRIA, Va., April 7 -- United States Patent no. 12,598,406, issued on April 7.
"Control of ONU activation in high bit rate PONs" was invented by Doutje Van Veen (New Providence, N.J.) and Vincent Houtsma (New Providence, N.J.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method and apparatus is proposed for performing the ONU activation process in a PON having a standard line rate of 50G or higher. The method and apparatus are based upon having the OLT instruct any activating ONUs to transmit at a line rate that is less than 50G, which allows for an OLT receiver without any particular equalization configuration to accurately recover the upstream burst-mode transmissions from the activating ONUs.
