Abstract

EN LA TRANSMISION OPTICA DE UNA SEÑAL DIGITAL A TRAVES DE UN CONDUCTOR (3) DE FIBRA OPTICA AFECTADO DE DISPERSION DE LONGITUD DE ONDA DE SERVICIO CON UN EMISOR (2) OPTICO, CUYA SEÑAL DE SALIDA ES MODULADA EN FRECUENCIA (AQUI MODULACION FSK) POR MEDIO DE LA SEÑAL DIGITAL, LLEGA AL EXTREMO DEL TRAMO DE CONDUCTOR DE FIBRA OPTICA CON UN PARAMETRO INCREMENTO DE T DIFERENTE EN CUANTO AL TIEMPO DE RECORRIDO DE AMBOS TRENES DE ONDA, QUE SUCEDEN EN LA MODULACION FSK. LA SEÑAL DE SALIDA V ELECTRICA DE UN CONVERTIDOR (5) OPTICO-ELECTRICO SE ENCUENTRA EN EL LADO RECEPTOR MODULADA EN SU INTENSIDAD Y RECORRE TRES ZONAS DE VALORES. PARA RECUPERAR DE NUEVO LA SEÑAL DIGITAL, SE UTILIZA SEGUN LA INVENCION UN CIRCUITO (6), CUYA SALIDA RECIBE UN PRIMER ESTADO, CUANDO UN VALOR DE EXPLORACION SE ENCUENTRA EN LA PRIMERA ZONA DE VALORES, CUYA SALIDA TOMA UN SEGUNDO ESTADO, CUANDO UN VALOR DE EXPLORACION SE ENCUENTRA EN LA SEGUNDA ZONA DE VALORACION, Y CUYA SALIDA TOMA EL ESTADO O SITUACION, EN EL QUE N BITS APARECEN ANTES DE LA MISMA SALIDA, CUANDO UN VALOR DE EXPLORACION SE ENCUENTRA EN EL TERCER CAMPO DE VALORACION.
