The Atlantic Crossing-1 (AC-1) submarine cable is a transatlantic telecommunications cable that connects the United States and the United Kingdom. It was first launched in 1998 and has since undergone several upgrades to improve its capacity and reliability.
The cable spans a distance of approximately 5,400 kilometers and has a capacity of 640 Gbps. It consists of eight fiber pairs, each with a capacity of 80 Gbps. The cable also features advanced repeaters to boost the signal and maintain the quality of transmissions.
AC-1 is operated by a consortium of telecommunications companies, including AT&T, BT, and Verizon. The cable provides high-speed connectivity for voice, video, and data communications between the two countries. It is primarily used for internet and phone traffic, connecting major cities such as New York, London, and Manchester.
The maintenance of AC-1 is carried out regularly to ensure the cable remains in good working condition. In case of any issues, repair crews are dispatched immediately to fix any faults that may arise. AC-1 has proved to be a reliable and vital asset to the telecommunications industry and continues to provide crucial connectivity between the United States and the United Kingdom.
