Abstract

DISPOSITIVO CON AMPLIFICADOR OPTICO DE FIBRA, EN EL QUE SE HA PREVISTO UN CIRCUITO REGULADOR PARA ESTABILIZAR LA AMPLIFICACION. EN EL CIRCUITO REGULADOR SE ALIMENTA A LA ENTRADA DEL AMPLIFICADOR DE FIBRA, DENTRO DE SU ANCHURA OPTICA DE BANDA DE AMPLIFICACION, UNA SEÑAL OPTICA ADICIONAL (Z). SU NIVEL ESTA CONTROLADO POR UN ELEMENTO DE CONTROL (Q), A CUYA PRIMERA ENTRADA SE ALIMENTA UNA PRIMERA SEÑAL DE MEDICION (M1), QUE REPRESENTA EL NIVEL DE UNA SEÑAL OPTICA AMPLIFICADA POR EL AMPLIFICADOR DE FIBRA (V) PROCEDENTE DE UNA PRIMERA ZONA DE LA ANCHURA DE BANDA DE AMPLIFICACION. EN LA SEGUNDA ENTRADA DEL ELEMENTO DE CONTROL SE HA SITUADO UNA SEGUNDA SEÑAL DE MEDICION (M2), QUE REPRESENTA EL NIVEL DE UNA SEÑAL OPTICA TODAVIA NO AMPLIFICADA PROCEDENTE DE UNA SEGUNDA ZONA DE LA ANCHURA DE BANDA DE AMPLIFICACION.
