"Have you ever wondered how an email sent from New York arrives in Sydney in
mere seconds, or how you can video chat with someone on the other side of the
globe with barely a hint of delay? Behind these everyday miracles lies an
unseen, sprawling web of undersea cables, quietly powering the instant global
communications that people have come to rely on.
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 global internet, carrying the bulk of
international communications, including email, webpages and video calls. More
than 95% of all the data that moves around the world goes through these
undersea cables.
These cables are capable of transmitting multiple terabits of data per second,
offering the fastest and most reliable method of data transfer available today.
A terabit per second is fast enough to transmit about a dozen two-hour, 4K HD
movies in an instant. Just one of these cables can handle millions of people
watching videos or sending messages simultaneously without slowing down.
About 485 undersea cables totaling over 900,000 miles sit on the the ocean
floor. These cables span the Atlantic and Pacific oceans, as well as strategic
passages such as the Suez Canal and isolated areas within oceans."
