Abstract

AMPLIFICADORES DE FIBRAS OPTICAS (3), COMO SON UTILIZADOS EN SISTEMAS DE TRANSMISION OPTICOS, COMO POR EJEMPLO, AQUELLOS CONDUCTORES DE FIBRAS OPTICAS DOTADOS DE ER3+, DISPONEN EN EL MARGEN DE LA LONGITUD DE ONDA INTERESANTE, UNA FUERTE DEPENDENCIA DE LA AMPLIFICACION DE LA LONGITUD DE ONDA. SEGUN LA INVENCION, SE AJUSTA LA LONGITUD DE ONDA DE EMISION (LAMBDA O) DEL LASER SEMICONDUCTOR (1), DE UN SISTEMA DE TRANSMISION OPTICO, POR MEDIO DE UN DISPOSITIVO DE REGULACION EXISTENTE EN EL EMISOR OPTICO (20), A AQUELLA LONGITUD DE ONDA, EN LA QUE LOS AMPLIFICADORES DE FIBRAS OPTICAS (3) AMPLIFICAN DE FORMA MAXIMA. EL DISPOSITIVO DE REGULACION ENCUENTRA LA LONGITUD DE ONDA OPTIMA, CUANDO LA ABSORCION DE LUZ DE UN CONDUCTOR DE FIBRAS OPTICAS DE REFERENCIA (9), ENCUENTRA SU MAXIMO EN LA MISMA LONGITUD DE ONDA, EN EL QUE EL AMPLIFICADOR DE FIBRAS OPTICAS (3) TIENE SU AMPLIFICACION MAXIMA, LAS EVALUA Y LA LONGITUD DE ONDA DE EMISION DEL LASER (1) SE AJUSTA A LA LONGITUD DE ONDA DE LA MAXIMA ABSORCIONEN EL CONDUCTOR DE FIBRAS OPTICAS DE REFERENCIA (9).
