The construction of a new submarine cable linking Sweden and Finland has officially begun, GlobalConnect, a leading digital infrastructure provider in the Nordic region.
The initiative is designed to enhance data transmission capacity across the Baltic region. According to GlobalConnect, the project responds to the rapidly growing demand for secure, high-capacity fiber infrastructure, driven by the expansion of major data centers and emerging artificial intelligence hubs in the Nordics.
“Adding new routes in and out of the Nordics is not only about transmitting more data — it also ensures vital redundancy,” said Par Jansson, senior vice president at GlobalConnect Carrier, stressing that it reduces the risk of disruptions or deliberate damage, and ensures data traffic can continue even if one route is compromised.
In addition to the 150-kilometer submarine cable, GlobalConnect will also upgrade its terrestrial infrastructure. This includes the installation of approximately 365 kilometers of new fiber-optic cable spanning from Helsinki to southwestern Finland’s Turku, through the Aland Islands (an autonomous region of Finland), and from Stockholm to Gavle in eastern Sweden — increasing capacity for higher volumes of data traffic.
The total investment in the project is estimated at 14 million euros (16.46 million U.S. dollars). Marine seabed surveys in the Baltic Sea began in the first half of 2025, with the cable expected to be operational by the end of 2026. (1 euro = 1.18 U.S. dollar)
