Abstract

RED OPTICA DE COMUNICACIONES. PARA EL ACCESO DE ABONADOS, MEDIANTE FIBRA OPTICA, A REDES DE COMUNICACIONES QUE PROPORCIONAN DIVERSOS TIPOS DE SERVICIOS, POR MEDIO DE UN NODO DE ACCESO (AN) OPTICO. LAS CONEXIONES ENTRE LOS EQUIPOS DE TERMINACION DE RED (ONT), A LOS QUE SE CONECTAN LOS ABONADOS, Y EL NODO DE ACCESO (AN) SE PUEDEN REALIZAR MEDIANTE ENLACES PUNTO A PUNTO O MULTIPUNTO A PUNTO MEDIANTE FIBRA OPTICA. LOS ENLACES ENTRE EL NODO DE ACCESO (AN) Y LA CENTRAL DE CONMUTACION (CE) SE REALIZAN MEDIANTE FIBRAS OPTICAS POR LAS QUE SE TRANSMITEN LAS SEÑALES OPTICAS CORRESPONDIENTES A UN NUMERO DE ABONADOS, MULTIPLEXADOS POR DIVISION EN LONGITUD DE ONDA. DICHA RED PERMITE EL ACCESO A TODO TIPO DE SERVICIOS DE COMUNICACIONES DONDE CADA TIPO DE SERVICIO EMPLEA, PARA SU CONEXION ENTRE EL NODO DE ACCESO (AN) Y EL EQUIPO DE TERMINACION DE RED (ONT) UNA LONGITUD DE ONDA RESERVADA. DICHA LONGITUD DE ONDA ES FIJA Y SOLO DEPENDE DEL TIPO DE SERVICIO.
