The Blue submarine cable is a high-capacity undersea fiber optic cable that runs across the Atlantic Ocean, connecting the United States and Europe. The cable spans a distance of approximately 6,800 kilometers (4,225 miles) and has a capacity of 128 terabits per second.
The Blue cable was built by a consortium of telecommunications companies including Microsoft, Facebook, and Telxius. The cable was completed in 2018 and went into operation in early 2019. It is the first cable to connect the United States directly with Spain.
The Blue cable is designed to meet the growing demand for internet connectivity and is expected to provide faster and more reliable connections between the United States and Europe. The cable is also expected to improve the resiliency of the global internet infrastructure by providing an alternative route in the event of disruptions to existing cables.
Overall, the Blue submarine cable is a significant technological achievement and represents a major step forward in the development of global telecommunications infrastructure. It is expected to play an important role in shaping the future of internet connectivity and information exchange around the world.
