The pressure of sea water, the surge of ocean currents, and the activities of marine life may all pose potential threats to optical cables; at the same time, there are many types of operations on the sea surface, such as ship navigation, marine engineering construction, etc. These activities will bring greater fluctuations to the marine environment, further increasing the risk of damage to submarine optical cables.

[0003] At present, due to the limitations of technology and actual conditions, it is difficult to conduct comprehensive and effective supervision of the conditions of optical cable lines. On the one hand, the underwater environment is difficult to observe directly, and it is impossible to grasp the status of the optical cable in real time; on the other hand, the monitoring equipment and technical means are relatively limited, and it is difficult to accurately determine whether there is a problem with the optical cable; once a submarine optical cable fails, it becomes extremely difficult to determine its specific location. Due to the vastness and depth of the ocean, locating the fault point requires a lot of time and resources. Moreover, even if the fault location is determined, the repair work also faces many challenges. The harsh underwater environment, complex repair process and long operation time make it difficult to repair submarine optical cable failures in a timely manner, which brings great inconvenience and loss to communication and data transmission.
