A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea.

Submarine cables provide the primary means of connectivity – voice, data and Internet – between the United States and the rest of the world as well as connectivity between the mainland United States and consumers in Alaska, Hawaii, Guam, American Samoa, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands.

A submarine communications cable is a cable laid beneath the sea to provide telecommunication links between countries. The first such cables carried telegraphy traffic. Subsequent generations of cables carried telephone traffic, then data communications traffic.

2024年11月15日 · Submarine cables, also called undersea cables, sea cables, or underwater cables, are long, durable cables laid across the seabed. These cables can transmit data and electricity between continents and countries.

2024年4月12日 · Beneath the relentless waves and vast expanse of the ocean lies a critical artery of global communication: submarine communication cables. These undersea paths, hidden from view, connect continents and facilitate nearly all of our international data transmission.

2021年8月26日 · Subsea or submarine cables are fiber optic cables that connect countries across the world via cables laid on the ocean floor. These cables – often thousands of miles in length – are able to transmit huge amounts of data rapidly from one point to another.

2024年3月5日 · Submarine cables clearly play a critical role in global communications. For the United States, they provide connectivity between the contiguous United States and Alaska, Hawaii, American Samoa, Guam, the Northern Marianas, Puerto Rico, and the U.S. Virgin Islands – as well as connectivity with the rest of the world.

2024年4月1日 · Undersea cables, also known as submarine communications cables, are fiber-optic cables laid on the ocean floor and used to transmit data between continents. These cables are the backbone of the...

2022年9月13日 · Telecommunications providers have used undersea cables (also known as submarine or subsea cables) for long-distance communications for more than 170 years. The English Channel Submarine Telegraph Company laid the first undersea cable in 1850 between England and France, to enable international communications over telegraph.

What is a Submarine Communications Cable? The common and consistent components of any Submarine Communications Cable are the fibre optics, strands of glass, not much thicker than your hair. Data can be transmitted along these strands via wavelengths of light, at the speed of light and over hundreds of kilometres without interference.
