Abstract
ESTA INVENCION SE REFIERE A AMPLIFICADORES FOTONICOS, EJ. AMPLIFICADORES DE FIBRAS, QUE SON ESPECIALMENTE ADECUADOS PARA UTILIZARLOS EN ENLACES OPTICOS DE TELECOMUNICACIONES DE LARGA DISTANCIA. EL AMPLIFICADOR INCLUYE UN TRANSMISOR OPTICO, ADAPTADO PARA PROPORCIONAR A LA SALIDA DEL AMPLIFICADOR UNA SEÑAL POR DEFECTO QUE SE MODULA DIGITALMENTE Y LA MODULACION DIGITAL INCLUYE LA IDENTIDAD DEL AMPLIFICADOR. EL ESTADO POR DEFECTO SE CONSTITUYE CUANDO LAS SEÑALES DE TRAFICO CAEN POR DEBAJO DE UN NIVEL PREESTABLECIDO, EJ. EN EL CASO DE UNA ROTURA DE CABLE CUANDO LA SEÑAL CAE A CERO. EN UN ASPECTO PREFERENTE DE LA INVENCION, LAS SEÑALES DE TRAFICO SE MODULAN CON UN TONO DE CONTROL QUE SE UTILIZA PARA CONTROLAR LOS CAG DEL ENLACE DE TELECOMUNICACIONES. EN ESTE SISTEMA, EL ESTADO POR DEFECTO SE CONSTITUYE CUANDO EL NIVEL DEL TONO DE CONTROL CAE POR DEBAJO DE UN NIVEL PREDETERMINADO, Y LAS SEÑALES POR DEFECTO TAMBIEN CONTIENEN UN TONO DE CONTROL, DE TAL MODO QUE LOS AMPLIFICADORES SUBSIGUIENTES SE MANTIENEN FUERA DEL ESTADO POR DEFECTO.
