Abstract

EN UN RECEPTOR OPTICO PARA LA TRANSMISION OPTICA DE NOTICIAS SE DA EL PROBLEMA DE LA NECESIDAD DE UNA ZONA DINAMICA ELEVADA, PUESTO QUE EL RECEPTOR TIENE QUE ESTAR EN CONDICIONES DE EMPLEAR SEÑALES OPTICAS CUYOS NIVELES PUEDEN FLUCTUAR FUERTEMENTE TRAS EL LUGAR DE APLICACION. SEGUN LA INVENCION, ESTE PROBLEMA SE SOLUCIONA CON UN AMPLIFICADOR OPTICO, EN PARTICULAR UN AMPLIFICADOR OPTICO POR FIBRAS QUE RECORRE LA SEÑAL OPTICA ENTRANTE ANTES DE LA ENTRADA EN EL VERDADERO TRANSFORMADOR Y CUYO FACTOR DE AMPLIFICACION O AMORTIGUACION SE REGULA DEPENDIENDO DE LA SEÑAL ELECTRICA DE SALIDA DEL TRANSFORMADOR.
