Abstract

EN UN SISTEMA DE TRASMISION OPTICO CON UN AMPLIFICADOR (10) DE FIBRA OPTICA, QUE CONTIENE UN ACOPLADOR (12) DE FIBRA OPTICA SELECTIVO DE LONGITUD DE ONDA PARA EL ACOPLAMIENTO DE LUZ DE BOMBEO EN LA PIEZA DE FIBRA OPTICA (11) AMPLIFICADORA, SE TRASMITE SEGUN ESTE DESCUBRIMIENTO UNA SEÑAL OPTICA ADICIONAL, COMO POR EJEMPLO DE UN CANAL DE SERVICIO, DEL LUGAR DEL AMPLIFICADOR (10) DE FIBRA OPTICA EN EL QUE SE TRASMITE UNA U OTRA DIRECCION DE TRASMISION, EN LA QUE SE UTILIZA PARA LA MODULACION DE LA LUZ BOMBEADA. LA LUZ NO ES TOTALMENTE ABSORBIDA EN LA PIEZA DE FIBRA (11) AMPLIFICADORA, UNA CANTIDAD SUFICIENTE DE LA PIEZA DE FIBRA (11) ALCANZA EL CONDUCTOR DE ONDA DE LUZ (15) DEL SISTEMA DE TRASMISION OPTICA Y CONTINUA SOBRE ESTE HASTA EL PUNTO FINAL (A) DEL SISTEMA DE TRASMISION. ALLI ES DESACOPLADO Y CONDUCIDO SOBRE UN RECEPTOR OPTICO (17), FINALMENTE OBTENIDO DE NUEVO A TRAVES DE MODULACION DE LA SEÑAL ADICIONAL TRASMITIDA DE SU SEÑAL DE SALIDA. CON ELLO LA MODULACION DE LA FUENTE DE LUZ NO MODULA LA MODIFICACION DE LA PIEZA DE FIBRA (11) AMPLIFICADORA, SE MODULA PRIMERO LA SEÑAL ADICIONAL DE UNA ONDA PORTADORA CON BASTANTE ALTA FRECUENCIA Y A CONTINUACION LA FUENTE DE LUZ (13) CON LA SEÑAL DE MODULACION ORIGINADA.
