Rogue Optical Network Unit Mitigation in Passive Optical Networks

An optical line terminal (OLT) comprising:

• a source OLT channel termination (CT);
• and
• a target OLT CT in communication with the source OLT CT,
• wherein the target OLT CT is configured to transmit a tuning confirmation message to the source OLT CT after receipt by the target OLT CT of an upstream tuning response message from an optical network unit (ONU) indicating that upstream wavelength tuning of the ONU has been completed,
• wherein the target OLT CT is configured to transmit a broadcast notification message to all OLT CTs in the OLT, except for the target OLT CT, after transmitting the tuning confirmation message, and
• wherein the broadcast notification message indicates that the upstream wavelength tuning of the ONU is complete.

A method of tuning an upstream wavelength of an optical network unit (ONU), comprising:

• exchanging tuning messages with a target optical line terminal (OLT) channel termination (CT) to initiate upstream wavelength tuning of an ONU;
• transmitting a tuning request to the ONU after the tuning messages have been exchanged and receiving a tuning acknowledgement message from the ONU indicating that the tuning request will be executed;
• and
• transmitting a broadcast notification message to all other OLT CTs within the OLT after receipt of the tuning acknowledge message from the ONU, wherein the broadcast notification message includes a tuning time of the ONU.
