Abstract:
The present disclosure includes methods and systems in which idle tones are added at an ingress and terminated at an egress of a given fiberoptic communication link between ROADM nodes. An equalization process can be performed across the spectrum of available wavelength channels and then a determination can be made of a number of channels that can be added or dropped at a given time that meet a maximum threshold for change in power of the channels in the available wavelength. As channels without information-carrying signals are filled with idle tones, the stability of the optical system can be improved as there is less variability in power change when all of the channels have a substantially similar nominal power and a signal on one or more of those channels are added or removed.

Claim (Index 15):
An apparatus comprising:\n a wavelength-selective switch (WSS) for receiving a plurality of information-carrying signals each in a respective wavelength channel slot of a fiberoptic transmission link, wherein a number of the information-carrying signals is less than a total number of wavelength channel slots in the fiberoptic transmission link, and for coupling the plurality of information-carrying signals to an optical multiplexed section (OMS); and a light source coupled to the WSS to provide at least one idle tone in remaining wavelength channel slots not occupied by the information-carrying signals, so that all of the wavelength channel slots are occupied and wherein the at least one idle tone occupies any of the wavelength channel slots not containing information-carrying signals; wherein the WSS is configured to couple the plurality of idle tones to the OMS.
