Abstract
Un sistema para corregir la distorsion no lineal en sistemas de fibra optica incluyendo sistemas de comunicacion a través de la modulacion de luz provista por moduladores interferométricos tales como Mach-Zehnder. La presente invencion implica la adicion de una señal de correccion, la cual contiene informacion de cancelacion de error. El haz de luz optico de señal de correccion aditivo es cambiado en frecuencia o mezclado en fase a través del uso de una fase o modulador de frecuencia. Esto asegura la señal de luz de correccion que se añade incoherente o causiincoherentemente dentro de la anchura de banda de señal de interés. Además, el sistema de la presente requiere solamente de una fuente de luz individual y puede hacerse independiente de la longitud de onda y es fácilmente optimizado con dispositivos servo activos. Un sistema provisto por la presente invencion también proporciona una mejora sobre el estado de la técnica debido a su alto grado de correccion e independencia de la longitud del enlace utilizando fibras de modo individual, ordinarias.
