The Connection of the World

At present, over 90% of cross-border data transmission worldwide is carried out by submarine cables, which have become a dense network that extends in all directions and an indispensable component of world prosperity and economic development. The world is closely connected, promoting global exchange and integration of information, culture, and economy.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

In 1850, the French Anglo Telegraph Company laid the first submarine cable in human history across the English Channel between England and France, which could only send Morse telegraph codes at that time. Today, the research and development, production, and laying of submarine cables have a history of nearly 200 years, and their functions have undergone significant changes, becoming an important means of contemporary international communication. From the global distribution map of submarine cables, the laying density is very high, with numerous cables stretching across the vast and deep seabed, shuttling between the plains, canyons, and mountains of the seabed, like a giant network connecting the world. The landing location at both ends of the submarine cable is called the cable landing point. In addition to Hong Kong, Macao and Taiwan, the main Internet access in mainland China used to be only Shanghai, Qingdao and Shantou. After construction, Fuzhou, Xiamen and Hainan Island have been added. Some of these submarine cables connect neighboring countries at sea such as Japan, South Korea, Malaysia, and the Philippines, while others cross over.
