Transatlantic Cable

County Mayo is the landfall location for two transcontinental data communication fibre cables linking the USA with Europe. 

The first cable known as America-Europe Connect (AEC-1) was successfully connected in Killala Bay, North Mayo in 2015.  

The second cable known as America-Europe Connect 2 (AEC-2) is set to make landfall in Clew Bay at Oldhead, close to Westport in 2020. The subsea cables are owned and operated by Irish company Aqua Comms, which support global data centres, cloud-based networks and content providers.
