Abstract
Methods and systems for determining a receive signal quality of a new subcarrier group in an optical network, including a system in which each leaf node may report a current transmission output power to a hub node when it is determined that a receive signal quality of each of a plurality of subcarrier groups is within a required signal quality margin. A new leaf node may begin transmitting a new subcarrier group at a gradually increasing transmission output power until it reaches the required receive signal quality margin. The new leaf node gradually increases the transmission output power of the new subcarrier group until the hub node determines that any of the plurality of subcarrier groups and the new subcarrier group reached a maximum transmission output power or the signal quality of one or more of the plurality of subcarrier groups and the new subcarrier group begins to degrade.
