Abstract
SISTEMA DE COMUNICACIONES DIGITALES CON ACCESO MULTIPLE POR DIVISION EN EL TIEMPO MEDIANTE FIBRA OPTICA. COMPUESTO POR UNA CENTRAL (1) CONECTADA CON SUS EQUIPOS TERMINALES ASOCIADOS (3) POR MEDIO DE FIBRAS OPTICAS (4) Y DISTRIBUIDORES PASIVOS (2) BASADOS EN REDES DE UNA O DOS FIBRAS OPTICAS Y UTILIZANDO PARA ELLO TECNICAS DE MULTIPLEXACION POR COMPRESION EN EL TIEMPO O MULTIPLEXACION POR DIVISION EN EL TIEMPO, RESPECTIVAMENTE. DICHO SISTEMA TRANSMITE UNA ESTRUCTURA DE TRAMA DE LONGITUD FIJA QUE COMPRENDE UN CAMPO DE CANALES COMUNES PARA INTERCAMBIAR INFORMACION DE CONTROL, UN CAMPO DE CANALES DE INFORMACION PARA TRANSMITIR Y RECIBIR INFORMACION DE USUARIO Y UN CAMPO DE ALINEAMIENTO DE RAFAGAS QUE SE UTILIZA PARA EL PROCESO DE ALINEAMIENTO DE RAFAGAS PROCEDENTES DE LOS EQUIPOS TERMINALES ASOCIADOS (3) Y CON DESTINO A LA CENTRAL (1) DENTRO DE UNAS RANURAS DE TIEMPO PREVIAMENTE ASIGNADAS.
