Abstract

Se describe un sistema optico que incluye un transmisor laser analogo que tiene un modo operativo de rafaga. El sistema ademas incluye un controlador de energia que esta configurado para colocar el transmisor laser analogo en el modo operativo de rafaga cuando se proporciona una senal habilitada digital al controlador de energia. El controlador de energia comprende una fuente de voltaje de referencia un nodo a tierra, y un interruptor selector de entrada que esta configurado para seleccionar la fuente de voltaje de referencia cuando la senal habilitada digital es mantenida, y alternativamente, para seleccionar el nodo a tierra cuando la senal habilitada digital es des-mantenida. En una segunda modalidad ilustrativa, se describe un metodo para operar un transmisor laser analogo. El metodo comprende proporcionar una senal analoga al transmisor laser analogo, y una senal habilitada digital a un circuito controlador que esta acoplado al transmisor laser analogo. El metodo ademas comprende encender el transmisor laser cuando la senal habilitada es mantenida, y apagar el transmisor laser analogo cuando la senal habilitada es des-mantenida.
