Abstract

EN UN SISTEMA DE COMUNICACIONES DE FIBRA OPTICA (10), UN APARATO DE PARADA EN EL CASO DE UNA RUPTURA DEL CABLE DE FIBRA OPTICA, INCLUYE UN PRIMER CABLE DE FIBRA OPTICA (14) PARA PROPAGAR SEÑALES EN UNA PRIMERA DIRECCION (28), Y TIENE UNA DIVERSIDAD DE AMPLIFICADORES ADYACENTES (40), DISPUESTOS A LO LARGO DEL PRIMER CABLE (14). UN SEGUNDO CABLE DE FIBRA OPTICA (16), PARA PROPAGAR LAS SEÑALES EN UNA SEGUNDA DIRECCION (30), OPUESTA A LA PRIMERA (28), INCLUYE UNA DIVERSIDAD DE AMPLIFICADORES ADYACENTES (42) DISPUESTOS A LO LARGO DE DICHO SEGUNDO CABLE (16). CADA UNO DE LOS AMPLIFICADORES (42) EN EL SEGUNDO CABLE DE FIBRA OPTICA (16) ESTAN INTERCONECTADOS A UNO DE LOS AMPLIFICADORES (40) DEL PRIMER CABLE DE FIBRA OPTICA (14), PARA FORMAR UNA DIVERSIDAD DE PARES AMPLIFICADORES (46). LA CIRCUITERIA ESTA PREVISTA PARA EFECTUAR LA OPERACION DE REDUCCION DE NIVEL DE POTENCIA DE SALIDA DE UN AMPLIFICADOR (40,42) DENTRO DEL PRIMER Y SEGUNDO CABLES DE FIBRA OPTICA (14,16) EN CASO DE UNA RUPTURA DE CABLEENTRE PARES DE AMPLIFICADORES ADYACENTES (46), PARA QUE UN AMPLIFICADOR (40,42) DENTRO DE UN PAR AMPLIFICADOR (46) ADYACENTE A LA RUPTURA DEL CABLE CONCLUYA LA GENERACION O REDUZCA SU NIVEL DE POTENCIA A UN NIVEL DE SALIDA SEGURO. LA CIRCUITERIA (50,52) ESTA PREVISTA ADEMAS PARA GENERAR UN SEÑAL DE CONTINUIDAD EN LA SALIDA DE CADA UNO DE LOS AMPLIFICADORES (40,42) EN EL PRIMER Y SEGUNDO CABLE (14,16). LA CIRCUITERIA (60) ESTA PREVISTA PARA DETECTAR LA SEÑAL DE ELIMINACION DE CONTINUIDAD POR LA RUPTURA DEL CABLE, ACCIONANDO POR ELLO LA ENTRADA DEL AMPLIFICADOR (40,42) DENTRO DE UN PAR AMPLIFICADOR (46) ADYACENTE A LA RUPTURA DEL CABLE Y RESTABLECIENDO AUTOMATICAMENTE LA COMUNICACION A LO LARGO DEL CABLE PREVIAMENTE ROTO.
