Physical connections of submarine cables
Submarine communication cables are mainly used for communication services, which are expensive but highly confidential. Submarine power cables are mainly used for underwater transmission of high power electrical energy. They are equivalent to underground power cables. They are only the application occasions and the laying of the power cablesDifferent ways. As submarine cable engineering has been recognized as a complex and difficult large-scale project all over the world, complex technology has been applied to environmental survey, marine physics survey, cable design, manufacture and installationManufacturers in the world few, mainly Norway, Denmark, Japan, Canada, the United States, Britain, France, Italy and other countries, these countries in addition to manufacturing, but also to provide laying technology.At present, 220kV photoelectric composite submarine cable to break the foreign monopoly, to need not completely rely on imports.
Cable (submarine) is insulated wire wrapped in the submarine and river water, for telecommunications transmission. Modern submarine cables use fiber as a material to transmit telephone and Internet signals. The first submarine cable in the world was laid between England and France in 1850. China's first submarine cable was completed in 1888, a total of two, one is between Fuzhou, Sichuan, Shidao and Taiwan, Shanghai and Shanghai (fresh water), 177 nautical miles long, the other from Tainan Anping to Penghu, 53 nautical miles long.Submarine cables, submarine communication cables and submarine power cables.
Submarine cable (Undersea)Cable) a cable wrapped in insulating material and laid on the bottom of the ocean for telecommunication transmission. Submarine cables, submarine communication cables and submarine power cables. Modern submarine cables use fibre optics as materials to transmit telephonesInternet signals. The first submarine cable in the world was laid between England and France in 1850. China's first submarine cable was completed in 1888.
