[0002] Underwater optical cables, also known as submarine optical cables, are optical cable facilities that span the bottom of oceans and lakes for long-distance communications. They are an important part of the global communications network, supporting a large amount of data transmission needs such as the Internet, telephone services and financial transactions;

[0003] Existing underwater optical cables are usually composed of multiple layers, with the optical fiber at the center and a waterproof layer, a reinforcement layer and a protective layer on the outside. The optical fiber is the core of data transmission, while the other layers provide the necessary protection and mechanical strength to ensure the normal communication transmission of the underwater optical cable. However, in actual use, there are still the following defects:

[0004] During the laying process of underwater optical cables, two optical cables need to be fused and connected to increase the laying distance of underwater optical cables. After the two optical cables are fused and connected, a junction box needs to be used to position the two optical cables and to cover and seal the outside of the connection between the two optical cables. The existing junction box usually includes a bottom shell and a top cover, and a sealing gasket is provided between the bottom shell and the top cover. When in use, the two optical cables are positioned through the bottom shell, the sealing gasket is placed on the bottom shell, the top cover is inserted on the bottom shell, and then the bottom shell and the top cover are fixed by screws. The overall operation is relatively troublesome;

[0005] Therefore, the present application proposes an underwater long-distance communication optical cable. Utility Model Content
