Abstract
CONMUTADOR PROTECTOR DE UNA LINEA OPTICA DE TELECOMUNICACIONES CON AMPLIFICADORES OPTICOS. LA LINEA DE TELECOMUNICACIONES COMPRENDE, AL MENOS, UNA ESTACION TERMINAL (1, 2) QUE TIENE UN TRANSMISOR DE SEÑALES OPTICAS (T1, T2) Y UN RECEPTOR DE SEÑALES OPTICAS (R1, R2), QUE ESTAN CONECTADOS OPERACIONALMENTE POR UN DISPOSITIVO DE PROTECCION AUTOMATICO (19) ADECUADO PARA DESCONECTAR DICHO TRANSMISOR (T1, T2) EN AUSENCIA DE UNA SEÑAL OPTICA RECIBIDA, AL MENOS, UNA LINEA DE FIBRA OPTICA (3, 4) PARA LA TRANSMISION DE LAS SEÑALES OPTICAS TRANSMITIDAS POR DICHO TRANSMISOR Y RECIBIDAS POR DICHO RECEPTOR, Y, AL MENOS, UN AMPLIFICADOR OPTICO (5) INCLUIDO EN DICHA LINEA (3, 4). A DICHO AMPLIFICADOR OPTICO (5) SE ASOCIAN MEDIOS (12) PARA LA DETECCION DE LA PRESENCIA DE ENERGIA LUMINICA DE ENTRADA Y MEDIOS (14) PARA PROVOCAR LA DESCONEXION DEL AMPLIFICADOR, QUE EN AUSENCIA DE ENERGIA LUMINICA DE ENTRADA ESTA CAUSADA POR DICHOS MEDIOS DE DETECCION (12) PARA INTERRUMPIR SUSTANCIALMENTE CUALQUIER EMISION DE ENERGIA LUMINICA POR PARTE DE DICHO AMPLIFICADOR OPTICO.
