Abstract

método e dispositivo para monitoração de sistema de cabo submarino. um método e um dispositivo para a monitoração de um sistema de cabo submarino no campo de comunicações são providos. o método inclui as etapas a seguir. um sinal ótico emitido por uma fonte ótica para um enlace de transmissão de um sistema de cabo submarino é dividido em dois percursos de sinais óticos, em que um percurso de sinais óticos serve como uma luz coerente local, e o outro percurso de sinais óticos é transformado por um deslocamento de frequência de percurso múltiplo e serve como percursos múltiplos de sinais óticos de detecção de diferentes frequências. um resultado de monitoração é obtido pela realização de uma detecção coerente, com a luz coerente, em sinais óticos retornados dos percursos múltiplos de sinais óticos de detecção de frequências diferentes. o dispositivo inclui uma fonte ótica, um módulo de deslocamento de frequência de percurso múltiplo e um módulo de coerência.
