Abstract

EL INVENTO ES UN ENLACE DE COMUNICACION OPTICO ATMOSFERICO DE ALTA DISPONIBILIDAD, ALTA TASA DE DATOS, CORTA GAMA Y MOVIL QUE SE PUEDE UTILIZAR PARA HACER UN PUENTE PROVISORIO CUANDO SE PRODUCE UNA ROTURA EN UNA RED DE FIBRA OPTICA BREVEMENTE, COMPRENDE DOS TRANSCEPTORES, UNO A CADA EXTREMO DE LA ROTURA, PARA ESTABLECER EL PUENTE EN UNA FIBRA OPTICA SECCIONADA MEDIANTE UN TRAYECTO DE TRANSMISION OPTICO ATMOSFERICO QUE SE PUEDE EXTENDER HASTA UNA DISTANCIA DE 5 MILLAS. NO ES NECESARIA UNA FUENTE DE LUZ ESPECIAL. LA LUZ TRASMITIDA A TRAVES DE LA ATMOSFERA ES LA LUZ DE BAJA POTENCIA EMITIDA DESDE EL EXTREMO DE UNA FIBRA OPTICA Y GENERADA POR UN REGENERADOR OPTICO QUE SE USA NORMALMENTE PARA PRODUCIR LUZ UNICAMENTE PARA LA TRANSMISION MEDIANTE UNA FIBRA OPTICA. LA LUZ SE EXPANDE Y SE ALINEA PARA LA TRANSMISION ATMOSFERICA Y LUEGO SE TRASMITE A UN RECEPTOR. EN ESTE, EL DIAMETRO DEL HAZ DE LUZ RECIBIDO SE REDUCE OPTICAMENTE ENFOCANDOLO EN EL EXTREMO DE UNA FIBRA OPTICA PARA ACOPLAR LA LUZ A LA FIBRA. LAS FIBRAS OPTICAS PARA EL TRANSMISOR Y EL RECEPTOR SE MONTAN EN UNA PLATAFORMA QUE REGULA EN TIEMPO REAL PARA OPTIMIZAR LA SEÑAL RECIBIDA. LA ALINEACION OPTICA SE MANTIENE AUTOMATICAMENTE GOBERNANDO EL TRANSMISOR CONTROLADO POR ORDENADOR Y AJUSTANDO EL RECEPTOR. LOS TRANSMISORES Y LOS RECEPTORES NO REQUIEREN OTRA COMUNICACION QUE EL HAZ DE LUZ ENTRANTE PARA MANTENER LA ALINEACION OPTICA Y NO REQUIEREN BITS ADICIONALES EN EL FLUJO DE DATOS PARA LA TELEMETRIA.
