La simulación se basa en un modelo constituido por las ecuaciones de razón y propagación para una fibra dopada con erbio. La manipulación de este sistema de ecuaciones nos permite hacer un reagrupamiento de los parámetros presentes en un EDFA, a los cuales hemos nombrado parámetros A, B, C, D, y pueden obtenerse experimentalmente a partir de una fibra dopada con erbio.
