The Jonah submarine cable is a fiber optic cable that stretches across the Atlantic Ocean, connecting the United States and Spain. The cable was installed in 2014 and spans a distance of approximately 6,000 kilometers. It is a joint project between Telefonica and Facebook, and was named after the biblical figure Jonah, who was swallowed by a whale. The Jonah cable is designed to provide high-speed internet connectivity and improve communication between Europe and the Americas. Its capacity is estimated to be around 10 terabits per second, making it one of the fastest submarine cables in the world. The Jonah cable is just one of many undersea cables that have been laid in recent years to improve global connectivity and increase internet speeds.
