Abstract: A system and method are described herein. The system comprises a wavelength selective switch having a minimum passband width; a processor; and a memory storing a datastore and processor-executable instructions that when executed cause the processor to: receive a connection request comprising an optical channel; determine an affinity group ID of an affinity group associated with the requested optical channel, the affinity group being associated with two or more adjacent optical channels having a combined channel width equal to or greater than the minimum passband width; create a loading group based on the two or more adjacent optical channels associated with the affinity group; receive a loading request to load the optical channel associated with the affinity group; and in response to receiving the loading request, load the two or more adjacent optical channels associated with the affinity group.
