Zusammenfassung: | A distortion circuit for linearizing third-, fifth-and seventh-order distortion components in a non-linear optical communication system includes at least one group of series connected diodes coupled to a common input terminal for receiving a signal source at one end and to an inductor and a capacitor at the other end, a resistance coupled to the common input terminal and a bias source for providing a bias current to the group of series connected diodes. The distortion circuit may be implemented as a predistortion circuit in the headend of the optical communications system or as a postdistortion circuit at the receiving end.
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. |
