The story

MAREA was jointly planned and funded by Microsoft and Facebook (now Meta) to secure high-capacity trans-Atlantic connectivity independent of congested New York cable corridors. Landed further south between Virginia Beach and Sopelana near Bilbao, the 6,605 km cable features eight fiber pairs and introduced open-cable architecture allowing partners to upgrade optical transponders independently. Completed in late 2017 and operated by Telefónica's Telxius, MAREA reached over 200 Tbps with advanced modulation, establishing Virginia Beach as a premier US East Coast subsea gateway.

Notable

  • Jointly funded by Microsoft and Meta (then Facebook) to provide dedicated high-capacity trans-Atlantic connectivity.
  • Constructed with 8 fiber pairs and initially designed for 160 Tbps, later upgraded to over 200 Tbps with advanced modulation.
  • Landed south of traditional North Atlantic cable routes to enhance trans-Atlantic network resilience against storms.
  • Operated and managed by Telefónica infrastructure subsidiary Telxius across 6,605 kilometers of Atlantic seabed.
