Abstract

EN LA TRANSMISION DE SEÑALES DIGITALES A TRAVES DE CONDUCTORES (3) DE ONDA DE LUZ, QUE TIENEN UNA DISPERSION CROMATICA CONSIDERABLE EN LAS LONGITUDES DE ONDA UTILIZADAS, LA LONGITUD DEL TRAMO DE TRANSMISION ES MUY LIMITADA, CUANDO LA SEÑAL DIGITAL A TRANSMITIR SE TRANSFORMA MEDIANTE MODULACION DE INTENSIDAD EN UNA SEÑAL OPTICA. SE UTILIZA PARA ELLO EN LUGAR DE LA MODULACION DE INTENSIDAD UNA MODULACION DE FRECUENCIA (TAMBIEN FSK= CONOCIDO COMO FREQUENCY-SHIFT-KEYING), DE FORMA QUE LA LONGITUD DE TRAMO SALVABLE SE AGRANDA DE FORMA CONSIDERABLE, NOTANDO TAMBIEN EN EL LADO DE RECEPCION LA EXISTENCIA DE UN RECEPTOR OPTICO APROPIADO PARA ELLO. SEGUN LA INVENCION SE UTILIZA UN RECEPTOR (4) OPTICO SENCILLO, QUE NO ES SENSIBLE A UNA MODULACION DE FRECUENCIA, SINO A UNA MODULACION DE INTENSIDAD. ESTO ES POSIBLE, PORQUE DEBIDO A LA DISPERSION CROMATICA DEL CONDUCTOR (3) DE ONDA DE LUZ Y CON ELLO LA DIFERENCIA DE TIEMPO DE PROPAGACION ORIGINADO DE LAS PORCIONES DE SEÑALES DE DISTINTA LONGITUDES (LANDA0, LANDA1) DE ONDA DE LA MODULACION DE FRECUENCIA DE PRINCIPIO EN EL CURSO DE LA TRANSMISION A TRAVES DEL CONDUCTOR (3) DE ONDA DE LUZ GENERA UNA VARIACION DE INTENSIDAD, CUYO CURSO CONTIENE LA SEÑAL DIGIAL A TRANSMITIR.
