Abstract

SISTEMA E MéTODO PARA TRANSMISSãO óTICA Um sistema ótico que inclui um transmissor a laser analógico que tem um modo operativo de rajada é mostrado. O sistema ainda inclui um controlador de potência que e configurado para colocar o transmissor a laser analógico no modo operativo de rajada, quando um sinal de habilitação digital for provido para o controlador de potência. O controlador de potência compreende uma fonte de voltagem de referência, um nó de aterramento e um comutador seletor de entrada que é configurado para selecionar a fonte de voltagem de referência, quando o sinal de habilitação digital for declarado e, alternativamente, para selecionar o nó de aterramento, quando o sinal de habilitação digital deixar de ser declarado. Em uma segunda modalidade de exemplo, um método de operação de um transmissor a laser analógico é mostrado, O método compreende a provisão de um sinal analógico para o transmissor a laser analógico, e um sinal de habilitação digital para um circuito de controlador que é acoplado ao transmissor a laser analógico. O método ainda compreende a ativação do transmissor a laser analógico, quando o sinal de habilitação digital for declarado e a desativação do transmissor a laser analógico, quando o sinal de habilitação digital deixar de ser declarado.
