Abstract
Un sistema de adaptador de entrada pasivo incluye un filtro de rechazo de banda externo conectado a una red externa; un adaptador de entrada conectado al filtro de rechazo de banda externo, un puerto de entrada que conecta el adaptador de entrada a la red externa; un acoplador direccional conectado al puerto de entrada; un dispositivo de separación de señal basado en la frecuencia conectado a una primera terminal y que comprende una terminal de paso alto, y una terminal de paso bajo; un divisor de señales conectado a la terminal de paso alto, donde el divisor de señales está configurado para estar conectado a uno o más tipos de dispositivos principales; y un puerto de salida de banda ancha conectado a una segunda terminal del acoplador direccional. La salida de banda ancha está configurada para estar conectada con uno o más tipos de dispositivos secundarios; el adaptador de entrada y el filtro de rechazo de banda externa están configurados para evitar que las señales de una banda de frecuencia asociada con las comunicaciones en la red producidas dentro de una red interna alcancen una red externa.
