Abstract
DISPOSITIVO E MÉTODO PARA MONITORAMENTO DE LINK DE FIBRA ÓPTICA. A invenção refere-se a um dispositivo e a um método executado pelo dispositivo para monitoramento de um link de fibra óptica. O método fornecido para monitoramento de um link de fibra óptica (300) compreende gerar (S101) um sinal de monitoramento usado para monitorar o link de fibra óptica, combinar (S102) o sinal de monitoramento gerado com um sinal de dados a ser transmitido sobre o link de fibra óptica, detectar (S103) retroespalhamento do sinal de monitoramento a partir do link de fibra óptica, detectar (S104) uma alteração na característica do sinal de monitoramento retroespalhado detectado, e determinar (S105), a partir da alteração detectada em característica, pelo menos um local ao longo do link de fibra óptica onde o sinal de monitoramento é modificado, e perda de sinal nesse local.
