Kablingsnett

Kablingsnett, also known as submarine communications cables, are vital infrastructure for global internet connectivity. These cables are laid on the ocean floor, connecting continents and enabling the transmission of data across vast distances. They are composed of optical fibers that carry digital information using light pulses, which travel at the speed of light, minimizing latency.

The first transatlantic cable was laid in 1858, but it was not until the late 20th century that the technology advanced to support the high-speed data transmission required for modern internet use. Today, kablingsnett plays a crucial role in facilitating international communication, commerce, and data exchange.

These cables are typically owned and maintained by private companies, although some are leased to telecommunications providers. They are laid by specialized vessels equipped with cable-laying machinery. Once installed, they are protected by rock-filled pipes or concrete to prevent damage from fishing trawlers and other underwater hazards.

Kablingsnett are not without their challenges. They are susceptible to damage from natural disasters such as earthquakes and underwater landslides, as well as from human activities like anchor dropping and cable theft. When a cable is damaged, it can disrupt internet connectivity for millions of users, highlighting the critical importance of these underwater highways.
