Abstract

La invención se dirige a la caracterización de un canal óptico, tal como una fibra óptica, en una red óptica. El método incluye calibrar un transmisor mediante la medición de su transmisor y cierre de ojo por dispersión (TDEC, en el caso de sistemas ópticos sin retorno a cero (NRZ) o de transmisor y cuaternario de cierre de ojo por dispersión (TDECQ, en el caso de sistemas ópticos de modulación de amplitud de pulso de 4 niveles (PAM4). Ese transmisor calibrado se utiliza para caracterizar el canal óptico que se está probando al proporcionar una medida de su cierre de ojo por tensión (SEC) o su cuaternario de cierre de ojo por tensión (SECQ). Se puede calcular un déficit de pérdida para el canal óptico restando el valor SEC o SECQ del valor máximo TDEC o TDECQ.
