We discuss the evolution of a perturbed soliton in an anomalously dispersive optical fiber. In so doing, the advantage of using a natural mathematical framework based on inverse scattering theory will be emphasized. Results obtained in this way will be contrasted with these obtained by using an alternative approach commonly known as the associate field formalism. The relative merits of the two techniques will be discussed, and in particular the latter will be shown to fail unless the initial radiation field respects certain symmetry requirements.
