Abstract
Systems and methods are provided for re-calibrating an in-service Optical Multiplex Section (OMS) while it is operating in an optical system. A method, according to one implementation, includes a step of analyzing a state of at least one component of the in-service OMS in an optical network, whereby the at least component may include, among other things, one or more fiber spans. Based on a need to re-calibrate the at least one component of the OMS, the method also includes the step of transitioning the OMS from an in-service mode to a maintenance mode to prepare the OMS for re-calibration. At this point, a re-calibration procedure can be performed. In response to completing the re-calibration procedure, the method includes the step of transitioning the OMS from the maintenance mode back to the in-service mode.
