How are marine optical cables welded?

According to Wikipedia, fiber optic cables are a type of telecommunications cable made of glass or plastic, using light to transmit signals.

According to Wikipedia, fiber optic cables are a type of telecommunications cable made of glass or plastic, using light to transmit signals. Long, thin fiber cable, the composition of transparent glass is equal to the diameter of a hair. They are arranged in bundles called fiber optic cables and are used to transmit signals over long distances. Unlike an electrically transmitted copper cable, optical fiber is less prone to noise, speed and transmission.

Unlike people who often think about welding marine fiber cables will be done by divers and machines diving to the sea floor. In fact, the work of welding fiber optic cables must be carried out on the water by specialized fiber-optic ships.

Divers also cannot dive to a deep seabed for several kilometers, but must use a specialized ship to win the fiber cable from the sea floor to the surface, then fix the cable end with a float. . After that, the cable car continues to find the remaining broken head of the cable line to conduct each fiber optic cable connection in the special technical room on board.

After completing the fiber optic cables, the protective cable bundle will be re-wrapped as it is and sprayed back to the seabed. However, the sprinkling process also requires specialized machinery to blow sand in the seabed, forming a slot to place the optical cable and covering the sand upwards to minimize the possibility of collisions.
