Abstract

SE SUMINISTRA UN APARATO AMPLIFICADOR OPTICO QUE COMPRENDE UN AISLADOR OPTICO Y ES APLICABLE A VARIAS MEDICIONES Y VERIFICACIONES DE SISTEMAS DE TRANSMISION OPTICOS QUE IMPLICAN LA TELECOMUNICACION BIDIRECCIONAL Y LA LUZ RETROGRESIVA. UN APARATO AMPLIFICADOR OPTICO TAL ESPECIFICAMENTE COMPRENDE UNA LINEA DE TRANSMISION OPTICA 3 PARA TRANSPORTAR UNA SEÑAL LUMINOSA P1, UN AMPLIFICADOR OPTICO 1 CONECTADO A UNA LINEA DE TRANSMISION OPTICA 2 PARA AMPLIAR UNA SEÑAL LUMINOSA P1 Y UN AISLADOR OPTICO 2 CONECTADO A LA LINEA DE TRANSMISION OPTICA 3 PARA SUPRIMIR LA OSCILACION DEL AMPLIFICADOR OPTICO 1 CAUSADA POR LA SEÑAL LUMINOSA P1 REFLEJADA, AL QUE SE AÑADEN LOS DISPOSITIVOS OPTICOS 4, 5 CONECTADOS A LA LINEA DE TRANSMISION OPTICA 3 PARA AISLAR Y COMBINAR LA SEÑAL LUMINOSA P1 Y LA LUZ RETROGRESIVA P2. COMO LA SEÑAL LUMINOSA Y LA LUZ RETROGRESIVA SE PUEDEN AISLAR INDEPENDIENTEMENTE Y COMBINAR JUNTAS EN UN APARATO AMPLIFICADOR OPTICO SEGUN LA INVENCION, SE PUEDE UTILIZAR PARA LA TELECOMUNICACION BIDIRECCIONAL, LA MEDICION Y LA VERIFICACION DE VARIOS SISTEMA DE TRANSMISION OPTICOS QUE UTILIZAN LUZ RETROGRESIVA Y OTRAS APLICACIONES.
