Abstract

ESTA INVENCION SE REFIERE A UN SISTEMA DE TRANSMISION OPTICA PARA TRANSMITIR SEÑALES MODULADAS ANALOGICAS VIA UNA FIBRA OPTICA DE TRANSMISION (TAL COMO SEÑALES DE TV AM-MODULADAS VIA UNA RED OPTICA LOCAL), EN LAS QUE ES IMPORTANTE QUE EL RUIDO SEA MINIMO. LA MODULACION EXTERNA DE LA SEÑAL DE LASER (A) ES PRECEDIDA MEDIANTE EL FILTRADO DE LA SEÑAL DE RUIDO AL MENOS EN EL INTERVALO DE FRECUENCIA DE LA SEÑAL DE MODULACION (M), CON EL RESULTADO DE QUE LA SEÑAL MODULADA (C) ESTA LIBRE DE RUIDOS. LA APARICION DE DISTORSIONES COMO CONSECUENCIA DE LA MODULACION EXTERNA POR MEDIO, POR EJEMPLO, DE UN MODULADOR MACH-ZEHNDE ESTA COMPENSADA MEDIANTE LA ADICION DE ARMONICOS INDUCIDOS NORMALMENTE POR DICHO MODULADOR SOBRE LA SEÑAL DE MODULACION EN OPOSICION DE FASE
