Submarine cables: The arteries of the global economy

Submarine cables play a pivotal role in the global digital infrastructure, facilitating the transmission of internet data, communications, and artificial intelligence across an extensive network of optical fibre cables extending for hundreds of thousands of miles beneath the ocean surface.

These cables establish vital connections among major continents and serve as conduits for the essential global resource of data.

Approximately 95% of the world’s internet traffic traverses these cables, covering an expansive distance of nearly 800,000 nautical miles within a market valued at $14bn. This intricate network facilitates a staggering $10tn in financial transactions daily.

These cables offer two key advantages: the capability to transmit massive amounts of data simultaneously and their cost-effectiveness.

They significantly contribute to global trade, empower businesses to promote themselves, facilitate transactions, and open global markets through e-commerce, overcoming challenges posed by distances.

Furthermore, reports highlight that robust and stable internet services foster collaboration and attract investments among countries.

In 2023, 43 additional submarine cable systems were active or under construction compared with the previous year. Subsea communication cables have 1,444 landing points that are active or in development and connect those cables to the land communication systems.
