Description

Technical Field

[0001] The utility model relates to the field of submarine cables, in particular to a waterproof box for placing submarine cables. Background Art

[0002] Submarine cables are cables wrapped in insulating materials, laid on the seabed and used for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables all use optical fiber as material to transmit telephone and Internet signals.

[0003] At present, one end of the submarine cable is usually placed inside a waterproof box. The current waterproof box can only play a waterproof role, but cannot position the submarine cable. In this way, the submarine cable is prone to movement and will affect normal use. For this reason, we propose a waterproof box for placing submarine cables to solve the above problems.
