Abstract

EL DISPOSITIVO PERMITE LA SELECCION DE UNA FUENTE DE DATOS ENTRE DOS FUENTES, Y LA REGULACION DE LA CORRIENTE LASER. CONSTA DE UN GENERADOR DE CORRIENTE (A) CONTROLADO POR UNA SEÑAL DE ACTIVACION (ACT) Y QUE SUMINISTRA UNA CORRIENTE LASER (I) REGULABLE POR UN ELEMENTO EXTERIOR, UN CIRCUITO DE SELECCION (B) ENLAZADO A DOS FUENTES DEDATOS, Y UN MODULADOR DE SALIDA (7) ENLAZADO EN SU ENTRADA CON EL GENERADOR DE CORRIENTE (A) QUE LE SUMINISTRA LA CORRIENTE LASER (I) Y CON EL CIRCUITO DE SELECCION (B) QUE LE SUMINISTRA LOS DATOS A EMITIR, Y EN SU SALIDA CON EL LASER AL QUE LE SUMINISTRA LA CORRIENTE LASER (I) MODULADA POR DICHOS DATOS A EMITIR. EN AUSENCIA DE DATOS A EMITIR, LA SEÑAL DE ACTIVACION TIENE UN VALOR TAL QUE BLOQUEA AL GENERADOR DE CORRIENTE (A) DE FORMA QUE EL LASER NO SE ALIMENTE.
