Abstract

PARA COMPENSAR DISTORSIONES DE SEÑAL NO LINEALES EN SISTEMAS DE TRANSMISION DE MENSAJE OPTICOS ANALOGICOS, QUE SE GENERAN CON MOTIVO DE LOS "LASER-CHIRPS" Y DE LA DISPERSION CROMATICA DE LOS CONDUCTORES DE ONDA DE LUZ, ES CONOCIDO UN ATENUADOR EN FORMA DE UN ELEMENTO LC, CUYA CAPACIDAD ESTA FORMADA A TRAVES DE UN DIODO DE CAPACIDAD. ESTE ATENUADOR DEBE SER AJUSTADO SEGUN DISTORSIONES DE SEÑAL CONSIDERABLES (GRAN LONGITUD DEL TRAMO DE TRANSMISION), DE FORMA QUE PUEDAN ESTAR EN SERVICIO CON UNA CAPACIDAD MAS GRANDE, CON LO QUE SE REDUCE SU ANCHURA DE BANDA. PARA PODER ATENUAR TAMBIEN SEÑALES CON ANCHURA DE BANDA (P.EJ. 600 MHZ) MAYORES Y CON DISTORSIONES CONSIDERABLES, LA INVENCION PRESENTA UN CIRCUITO CADENA LC CON ELEMENTOS LC COMO ATENUADOR SEGUN ESTA FORMA CONOCIDA. FORMACIONES ULTERIORES DE ESTA SOLUCION PROPUESTA ENCUENTRAN LA POLARIZACION ADECUADA DEL DIODO CAPACITIVO Y LA ESTABILIZACION DE LA MARCHA DE FRECUENCIA EN EL AJUSTE DE ATENUACION.
