Abstract

EL DISPOSITIVO DE COMPENSACION DE DISPERSION SE USA EN UNA RED OPTICA DONDE SE TRANSMITAN LAS SEÑALES DESDE UNA ESTACION PRINCIPAL (M) A UNA VARIEDAD DE ESTACIONES DE USUARIO (US1 A US3). COMPENSA LA DISTORSION DE LA SEÑAL OPTICA ANALOGA CAUSADA POR EL CHIRRIDO DE LASER DE UN LASER EN LA ESTACION PRINCIPAL (M) QUE GENERA LE MENCIONADA SEÑAL OPTICA ANALOGA Y LA DISPERSION FIBRILAR DE LA CONEXION DE FIBRA A TRAVES DE LA QUE SE TRANSMITE LA SEÑAL OPTICA. EL DISPOSITIVO INCLUYE UN DISPOSITIVO DE MEDICION A DISTANCIA (R) QUE GENERA UNA SEÑAL DE RESULTADOS (MS) INDICADORA DE LA DISTANCIA ENTRE LA ESTACION PRINCIPAL Y LAS ESTACIONES DE USUARIO Y QUE POSIBLEMENTE YA ESTE DISPONIBLE EN LA RED PARA LLEVAR A CABO EL RECORRIDO CUANDO LA MISMA RED TAMBIEN SE USA PARA TRANSMITIR SEÑALES DIGITALES DESDE LAS ESTACIONES DE USUARIO A LA ESTACION PRINCIPAL USANDO EL ACCESO MULTIPLE DE DIVISION DE TIEMPO. TAMBIEN INCLUYE UN CIRCUITO DE PROCESAMIENTO (PC) QUE, EN RESPUESTA A UN CHIRRIDO DE LASER DADO Y LA SEÑALRESULTANTE, PROPORCIONA UNA SEÑAL DE SINTONIZACION (V) PARA SINTONIZAR EL VOLTAJE PREDISPUESTO DE UN DIODO VARACTOR (VD) QUE ES PARTE DEL CIRCUITO DE COMPENSACION INSERTADO EN EL CAMINO DE SEÑAL ELECTRICA. EN UNA EJECUCION OPTIMA, EL DISPOSITIVO DE MEDICION (R) Y EL CIRCUITO DE PROCESAMIENTO (PC) ESTAN SITUADOS EN LA ESTACION PRINCIPAL (M), MIENTRAS EL DIODO VARACTOR (VD) ESTA SITUADO EN CADA ESTACION DE USUARIO.
