Marea is a joint project between Microsoft, Facebook, and telecommunications company Telxius.
Marea is the most technologically-advanced subsea cable to cross the Atlantic Ocean and is the first cable to connect Virginia and Spain – landing in Virginia Beach and Bilbao.
Being physically separate from other cables ensures more resilient and reliable connections for customers in the US and Europe, said the company.
The 6,600km cable, which weighs 4.65 million kilograms, can transmit up to 160 terabits of data per second.
That’s the equivalent of streaming 71 million high-definition videos simultaneously.
