Abstract
Disclosed herein are methods and systems for optimizing an optical signal in an optical network having a leaf node with a coherent optical transceiver configured to receive an optical signal continuously transmitted at a first output power from a hub node over a link. The leaf node may be provided with signal quality correction circuitry configured to determine a signal quality of the optical signal and send the signal quality to a processor of the hub node. The processor of the hub node may be configured to compare the signal quality of the optical signal to a target signal quality margin, determine that the signal quality is outside the target signal quality margin, adjust the first output power of the optical signal to a second output power different than the first output power, and continuously transmit the optical signal at the second output power.
