Abstract

Un sistema y método de transmision optica para reducir la distorsion no lineal causada por la interaccion de Modulacion de Autofase y Dispersion deVelocidad de Grupo. Un enlace optico incluye un transmisor para proveer senales a una primera longitudde onda optica, un transpondedor para convertir laprimera longitud de onda optica en una segunda longitud de onda optica, una pluralidad de extensiones de fibra de transmision optica y amplificadores de fibraoptica, un dispositivo de compensacion dedispersion y un receptor. El sistema opera a un nivel de potencia de entrada relativamente alto. El transponedorincluye un dispositivo para nivelar los flancos de los tiempos de subida y de bajada de impulsos opticos, tales como un atenuador eléctrico y filtro pasabajos,de modo que los impulsos de flanco agudo recibidos del transmisor se transforman en una forma Gaussiana. Un dispositivo de compensacion de la dispersion talcomo una retícula de fibra optica, también ayuda a mejorar el índice de error de bit como funcion de la sensibilidad del receptor no obstante una longitud deenlace optico de menos de 600 km.A system and method of optical transmission to reduce the non-linear distortion caused by the interaction of Autophase Modulation and Group Speed Dispersion. An optical link includes a transmitter to provide signals at a first optical wavelength, a transponder to convert the first optical wavelength into a second optical wavelength, a plurality of optical transmission fiber extensions and fiber optic amplifiers, a device for dispersion compensation and a receiver. The system operates at a relatively high input power level. The transponder includes a device for leveling the flanks of the rise and fall times of optical pulses, such as an electric attenuator and low pass filter, so that the sharp flank pulses received from the transmitter are transformed into a Gaussian form. A dispersion compensation device such as an optical fiber grid also helps improve the bit error rate as a function of the receiver's sensitivity despite an optical link length of less than 600 km.
