Abstract
A system for loading a fiber optic transport system includes a wavelength selective switch (WSS) having inputs and an output connected to an optical fiber, wherein the inputs are connected to one or more lines having data-bearing channels thereon; and an amplified spontaneous emission (ASE) generator connected to one of the inputs of the WSS, wherein the WSS is configured to perform a channel addition through substitution of an ASE channel from the ASE generator for a data-bearing channel, and a channel deletion through substitution of a data-bearing channel for an ASE channel from the ASE generator, and wherein, to limit perturbations on the optical fiber due to channel additions and deletions, the WSS is configured to limit a number of channels that are switched at a same time for a set of channel additions or deletions.
