Submarine Optical Fiber Cable



Submarine Optical Fiber Cable, also known as submarine communication cable, is a wire wrapped with insulating material and laid on the seabed to establish telecommunications transmission between countries.


Submarine cable system is mainly used to connect fiber optic cable and the Internet. It is divided into two parts: onshore equipment and underwater equipment. Submarine cable is the most important and most vulnerable part of underwater equipment.

With the rapid development of the ICT industry such as cloud computing, Internet of Things, big data, mobile internet, etc., the demand for connectivity from all over the world continues to increase.

In the process of moving towards a better all-coupling, the role played by the submarine cable is becoming more and more important and has become the cornerstone of the country's economic development, which has received the attention of the government and investors.


In January 2018, Google announced that it will build three new submarine cables to expand its global cloud computing business. Three submarine cables connect Hong Kong, the United States, Ireland, Denmark and Chile and are expected to be completed by 2019. In addition to the 8 fiber optic cables being used or constructed, Google’s submarine cable holds 11 pieces.
