Abstract
Methods and systems are herein disclosed, including a method comprising: receiving an amplified spontaneous emission (ASE) configuration message indicating that an optical network element has switched from a non-ASE mode to an ASE mode; retrieving a current spectrum layout identifying activated signal passbands (SPs); and setting start and end frequencies of at least one AP to a nonzero value based on the current spectrum layout, thereby marking the at least one AP as at least one eligible AP, the bandwidth of each of the at least one eligible AP not overlapping with the bandwidth of any of the activated SPs; wherein the optical network element is operable to activate the at least one eligible AP in an optical fiber link to produce at least one activated AP, thereby causing an ASE source to fill each of the at least one activated AP with ASE noise.
