Description

[0002] With the rapid development of global communication networks, submarine optical cables ("submarine cables") have become an important means of data transmission between different countries and regions. During the laying process of submarine cables, due to their length, which usually reaches thousands of kilometers, it takes a long time to complete the laying. During the laying process, multiple joints need to be connected to ensure the continuity and stability of the signal. Submarine cables are easily affected by ocean currents and swing, and the finished products are difficult to protect. Therefore, during the process, it is often necessary to temporarily fix the submarine cable joints to avoid the loss of submarine cable joints due to the influence of waves, because it is difficult to find the submarine cable after it is washed away.
