Abstract

Patente de Invenção: "PROCESSO PARA LIGAçãO DE UMA COMUNICAçãO DE EMERGêNCIA E/OU PARA DESLIGAMENTO DE SEGURANçA DE LASER EM DISPOSITIVOS DE TRANSMISSãO óPTICOS". No processo para ligação de emergência em dispositivos de transmissão ópticos, são transmitidos, além de um sinal de trabalho (WS1) e um sinal de proteção (PS1), respectivamente sinais de controle (CS1, CS2), com informações sobre o estado de bloqueio e avaliados no lado das recepção. Os sinais de controle são transmitidos através de um canal de controle, também ao sinal útil desligado.
