Rogue Optical Network Unit Mitigation in Multiple-Wavelength Passive Optical Networks

摘要

A method implemented in an optical line terminal (OLT) for reducing adverse effects from a rogue optical network unit (ONU) in a passive optical network (PON), comprising determining with a processor that the rogue ONU is transmitting in violation of pre-specified parameters, and sending at least one message to a plurality of ONUs to change a transmitting wavelength from a first wavelength to a second wavelength.
