Abstract

LA RED SEGUN EL INVENTO UTILIZA FIBRAS OPTICAS MONOMODO DE RECEPCION (101) DE EMISION (102) QUE EMPALMAN TERMINALES MEDIANTE UN ACOPLADOR DE ESTRELLA. HAY UN OSCILADOR LOCAL (106) EN CADA TERMINAL (100) PARA REALIZAR UNA RECEPCION HETERODINA. PARA EL INTERCAMBIO DE MENSAJES EN UN CANAL DE FRECUENCIA, LAS FRECUENCIAS DE LOS EMISORES (105,20) DE LOS TERMINALES INVOLUCRADOS Y LAS DE SUS OSCILADORS LOCALES (106,206) SE REGULAN LOCALMENTE, A PARTIR DE FRECUENCIAS DE CANALES ADYACENTES OCUPADOS POR OTROS INTERCAMBIOS DE MENSAJES O, EN SU DEFECTO, A PARTIR DE UNA FRECUENCIA BASE EMITIDA POR UN GENERADOR COMUN. ESTOS TERMINALES EFECTUAN PARA ELLO UN INCREMENTO DE FRECUENCIA GRACIAS A UN BARRIDO DE FRECUENCIA Y A UN RELOJ (125) ASI COMO A UNOS FILTROS (120,122,125) QUE PERMITEN LOCALIZAR UN CANAL DISPONIBLE. EL INVENTO SE APLICA EN LAS TELECOMUNICACIONES.
