MITIGATING ROGUE OPTICAL NETWORK UNIT (ONU) BEHAVIOR IN A PASSIVE OPTICAL NETWORK (PON)

摘要

Techniques, apparatus and systems are described for an optical line terminal (OLT) operable in a passive optical network (PON) system to isolate and mitigate the behavior of a rogue optical network unit (ONU) that transmits optical power up the optical distribution network (ODN). In one aspect, a method of mitigating the behavior of rogue ONUs can include detecting the presence of a rogue ONU on the PON system, and transmitting, based on the detection, a message addressed exclusively to the ONUs that have not yet been discovered or identified by the OLT.

1. A method, implementable at an optical line terminal (OLT) in a passive optical network (PON) system, to facilitate mitigation of rogue behavior of an optical network unit (ONU), the method comprising:
detecting presence of a rogue ONU on the PON system; and transmitting, based on the detection, a first message addressing only a subset of all ONUs on the PON system.
