Abstract

METODO DE TRANSMISION MULTICANAL DE INFORMACION DIGITAL Y VIDEO DE BANDA ANCHA EN UNA RED DE CIERRE LOCAL DE FIBRA OPTICA MEDIANTE MULTIPLEXACION POR DIVISION DE FRECUENCIA. COMPRENDE: A) GENERAR CONJUNTO DE PARES DE PORTADORAS OPTICAS SEPARADAS LIGERAMENTE QUE SE UTILIZAN PARA LA TRANSMISION SIMULTANEA DE INFORMACION DIGITAL Y ANALOGICA, TENIENDO LAS PORTADORAS OPTICAS DE CADA PAR DE PORTADORAS OPTICAS UNA PREDETERMINADA SEPARACION DE FRECUENCIAS ENTRE ELLAS; B) ASIGNACION DE PORTADORAS OPTICAS A UN INTERVALO DE FRECUENCIA DE LASERES DE TRANSMISION A FRECUENCIA DIFERENTES PARA EVITAR SOLAPAMIENTOS ESPECTRALES; C) COMBINACION OPTICA DEL CONJUNTO DE PARES DE PORTADORAS OPTICAS PARA TOMAR UNA SEÑAL OPTICA MULTIPLEXADA DE SALIDA.
