Classification: CPC H | IPC H

Claim 0:
1. A local controller associated with a local power compensation unit configured to adjust power levels of optical channels on a fiber span, the local controller comprising
a processing device, and
a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
determine whether an upstream controller is currently performing an upstream action, or intends to perform the upstream action soon thereafter, with respect to an upstream power compensation unit that is configured to adjust the power levels of the optical channels on an upstream fiber span connected to the fiber span, wherein the upstream action includes adjusting the upstream power compensation unit to adjust the power levels to compensate for power offsets in the optical channels at an output of the upstream power compensation unit,
determine whether there is a need to perform a local action with respect to the local power compensation unit, wherein the local action includes adjusting the local power compensation unit to adjust the power levels to compensate for power offsets in the optical channels at an output of the local output of the local power compensation unit, and
perform the local action with respect to the local power compensation unit in response to determining that
the upstream controller is not currently performing the upstream action, or does not intend to perform the upstream action soon thereafter, and
there is a need to perform the local action.
