USING NOISY WINDOW FOR UNCALIBRATED OPTICAL NETWORK UNIT ACTIVATION

摘要

A method of Noisy Window and associated management messages to support set splitting if activating ONUs with uncalibrated transmitter, offering a power grant for unmodulated upstream transmission, measuring the average received optical power in all upstream wavelength channels and providing downstream indication of the upstream activation in the optical communication network wavelength channel with abnormally high average received power.
