Abstract

SEGUN LA INVENCION, EL SISTEMA SIRVE PARA DISTRIBUIR SEÑALES DE NOTICIAS, EN PARTICULAR SEÑALES DE TELEVISION, DE UNA CENTRAL A MUCHOS ABONADOS Y POSIBILITAR UNA TRANSMISION BIDIRECCIONAL DE SEÑALES TELEFONICAS Y DE DATOS ENTRE LA CENTRAL Y LOS ABONADOS. SEGUN LA INVENCION, LA RED EMPLEADA PARA ESTO ES UNA RED DIRECTORA DE ONDAS DE LUZ CON ESTRUCTURA DE ESTRELLAS EN LA QUE SE PRESENTAN AMPLIFICADORES (10, 11) OPTICOS POR FIBRAS ENTRE LOS PUNTOS DE BIFURCACION QUE SE SIGUEN UNOS A OTROS. LAS SEÑALES DE NOTICIAS A DISTRIBUIR SE TRANSMITEN A LOS ABONADOS POR UNA RED DIRECTORA DE ONDAS DE LUZ CON UNA PRIMERA LONGITUD DE ONDA (11) Y LAS SEÑALES DE NOTICIAS A TRANSMITIR A LOS ABONADOS INDIVIDUALMENTE SE TRANSLADAN DE LA CENTRAL (1) A LOS ABONADOS (T SUB I) POR MEDIO DE UNA MODULACION DE FRECUENCIA EN OTRA BANDA DE FRECUENCIA (FB SUB 2) COMO SEÑALES DE DISTRIBUCION Y SE TRANSMITEN A LOS ABONADOS CON LA MISMA LONGITUD DE ONDA COMO LAS SEÑALES DE DISTRIBUCION, Y LAS SEÑALES A TRANSMITIR INDIVIDUALMENTE DE LOS ABONADOS (T SUB I) A LA CENTRAL (1) SE TRASLADAN POR MODULACION DE FRECUENCIA EN OTRA BANDA DE FRECUENCIA (FB SUB 3) Y SE TRANSMITEN OPTICAMENTE A LA CENTRAL CON UNA SEGUNDA LONGITUD DE ONDA (12). ESTA SEÑAL OPTICA SE FORTALECE EN LUGARES APROPIADOS (A) Y SE INDICAN VARIOS EJEMPLOS DE EJECUCION ALTERNATIVOS PARA ESTE FORTALECIMIENTO.
