Abstract

Un circuito de distorsion para linealizar componentes de distorsion del tercer, quinto y séptimo orden, un sistema de comunicaciones opticas no lineal, incluye cuando menos un grupo de diodos conectados en serie acoplados a una terminal de entrada comun, para recibir una fuente de señal de un extremo, y a un inductor y un condensador en el otro extremo, una resistencia acoplada a la terminal de entrada comun y una fuente de biasado para proporcionar corriente biasada al grupo de diodos conectados en serie. El circuito de distorsion se puede implementar como un circuito de distorsion previa en el extremo cabezal del sistema de comunicacionesopticas, o como un circuito de distorsion posterior en el extremo de recepcion.
