Abstract
Systems, methods, and non-transitory computer-readable media are provided for performing channel swapping techniques for swapping bundles of optical channels in an optical network, such as a C+L band system, based on frequency band sensitivity. In one embodiment, a method includes swapping a first group of channels or first portion of spectrum in a more-sensitive frequency band with a first set of replacement channels or first portion of replacement spectrum using a first swapping technique. The method also includes swapping a second group of channels or second portion of spectrum in a less-sensitive frequency band with a second set of replacement channels or second portion of replacement spectrum using a second swapping technique that is different from the first swapping technique. The first and second swapping techniques are based at least in part on the number of channels or portion of spectrum that can be swapped at any given time instance.
