Submarine Optical Fibre (Fiber) Cable, also known as submarine communication cable.
It is a wire wrapped with insulating material, laid on the seabed, and used to set up telecommunications transmission between countries.
The submarine optical cable system is mainly used to connect fiber optic cable and the Internet, it is divided into two major parts of shoring equipment and underwater equipment, the submarine optical cable is the most important and vulnerable part of the underwater equipment.
The laid submarine cables are generally available in medium voltage and high voltage submarine cable in terms of voltage. The cable DC voltage is rated at 200kV.
These DC submarine power cables are used for power transmission to offshore islands, oil platforms, or to cross rivers and lakes.
ZMS Cable design is based on the major national or international standards e.g. VDE, IEC, and ICEA, or according to customers' design and standards.
