Abstract

UNA RED DE DISTRIBUCION RF Y TV PARA LA DISTRIBUCION DE UNA SEÑAL FDM CON ALTO INDICE DE CANAL A TRAVES DE FIBRA DE VIDRIO, CON UNA ESTACION EN LA QUE SE TRANSFORMAN EN FRECUENCIA LAS SEÑALES DE CANALES M Y SE JUNTAN CONJUNTAMENTE A LAS SEÑALES FDM, QUE SE ALIMENTAN A LA RED EN UNA TRANSFORMACION ELECTROOPTICA, CON EQUIPOS PARTICIPANTES, EN DONDE DESPUES DE LA TRANSFORMACION ELECTROOPTICA LA SEÑAL FDM SE ELABORA EN LAS SEÑALES DE CANAL INDIVIDUALES DE TAL MODO QUE EL PARTICIPANTE PUEDE AGARRARSE A UN DE ELLAS, CARACTERIZANDOSE PORQUE OTRA ESTACION SI ESTA PREVISTA EN LA RED. DESPUES DE LA TRANSFORMACION ELECTROOPTICA LA SEÑAL FDM QUE LLEGA SE ELABORA DE TAL MODO, QUE LAS SEÑALES DISPONEN DE UNA CANTIDAD ADICIONAL DE OTROS CANALES O DE CANALES DE FRECUENCIA LIBRES EN LUGAR DE CANALES QUE POSEEN A ELECCION SEÑALES LIBRES SIENDO COLOCABLES EN LA NUEVA SEÑAL FDM. LOS SISTEMAS DE DISTRIBUCION, RECONFIGURABLES EN CUALQUIER POSICION Y FLEXIBLES, GARANTIZAN INTERCAMBIO LOCAL DE PROGRAMAS Y ABASTECIMIENTO OPTIMO DE UNA ZONA MEDIANTE LA CONSERVACION DE BUENAS CUALIDADES DE SEÑAL POR MEDIO DE UTILIZACION DE PASO ACCESIBLE DE ELABORACIONES DE SEÑAL DIGITALES.
