Speaking of submarine communication, its history is 100 years earlier than the Internet, but the submarine communication at that time was still realized by cables. In 1850, the Anglo-French Telegraph Company began to lay the world's first submarine cable between Britain and France. At that time, only Morse telegram codes could be sent; and in 1866, the British laying of all the cables between the United States and Britain became the successful laying of trans-Atlantic submarine cables, realizing for the first time trans-Atlantic telegraph communication between European and American continents. Subsequently, Bell invented the telephone in 1876, and people's dreams of realizing global communication became stronger and stronger, which also accelerated the construction of global submarine cables-the global submarine communication cable was completed in 1902.

      Speaking of my country’s first submarine cable, it can be traced back to the Qing Dynasty. At that time, Taiwan’s first governor, Liu Mingchuan, began to lay waterways connecting the entire island of Taiwan and the mainland in 1886 in order to realize cross-strait telegraph communication, and in 1888. Completed in the year, one of them is the waterway between Chuanshidao Island in Fuzhou and Huwei in Taiwan, and the other is the waterway between Anping, Tainan and Penghu.
