Abstract
"PROCESSOS PARA INTERROMPER FUNCIONAMENTO DE UM SISTEMA DE COMUNICAçãO óPTICO E PARA INICIALIZAR UMA LINHA óPTICA DESATIVADA DENTRO DE UM SISTEMA DE COMUNICAçãO óPTICO, E, SISTEMA DE CONTROLE SUPERVISOR PARA UMA LINHA DE COMUNICAçãO óPTICA" Um sistema de comunicação óptico e processo para inicializar e interromper funcionamento do sistema para garantir segurança durante reparo de uma ruptura de fibra são expostos. Uma técnica para interromper funcionamento de um sistema de comunicação óptico tendo extensões de fibra de transmissão óptica intercaladas serialmente entre locais de transformação óptica e uma pluralidade de locais de amplificador inclui interrupção de funcionamento de ambos amplificadores tanto no lado de uma ruptura de fibra e ambos amplificadores nos mesmos locais de amplificador servindo transmissão em uma direção oposta, seguido por desativação de todos os amplificadores dentro da mesma linha óptica entre locais de transformação óptica. Durante inicialização, amplificadores entram em um modo de operação para ignorar um sinal de interrupção de funcionamento de sistema, um amplificador em um local terminal é forçado a ligar, e então sucessivos amplificadores progridem através de um nível de potência segura intermediária antes de alcançar total potência de operação."PROCESSES TO INTERRUPT FUNCTIONING OF AN OPTICAL COMMUNICATION SYSTEM AND TO INITIALIZE AN OPTICAL LINE OFF WITHIN AN OPTICAL COMMUNICATION SYSTEM, AND, SUPERVISOR CONTROL SYSTEM FOR AN OPTICAL COMMUNICATION LINE" An initial communication system and process to initiate an optical communication and process to initiate an optical communication process and to initiate an optical communication process and to interrupt the initial communication and process. functioning of the system to ensure safety during repair of a fiber break are exposed. A technique for interrupting operation of an optical communication system having optical transmission fiber extensions serially interleaved between optical transformation locations and a plurality of amplifier locations includes interrupting the operation of both amplifiers on both the side of a fiber break and both amplifiers in the same amplifier locations serving transmission in the opposite direction, followed by deactivation of all amplifiers within the same optical line between optical transformation locations. During startup, amplifiers enter an operating mode to ignore a system interruption signal, an amplifier at a terminal location is forced to turn on, and then successive amplifiers progress through an intermediate safe power level before reaching full power of operation.
