Mjolner East

Overview

Mjolner East is a regional submarine cable system spanning approximately 450 km across the eastern Baltic Sea. It connects Estonia, Finland, and Sweden, serving the corridor between the Gulf of Finland and the broader Baltic region. The cable is owned and operated by GlobalConnect, a Nordic telecommunications infrastructure provider.

Route and Landings

In Estonia, Mjolner East lands at two points: Kihelkonna and Tallinn. These landings provide connectivity to the western coast and the capital of Estonia respectively.

In Finland, the cable lands at Helsinki, the country's capital and primary telecommunications hub on the southern coast.

In Sweden, the cable comes ashore at Farosund, located on the island of Gotland in the Baltic Sea.

Ownership and Operators

Mjolner East is solely owned by GlobalConnect. GlobalConnect is a Nordic infrastructure company providing fiber and data center services across the northern European market.

Status and Timeline

Mjolner East is planned for service with a Ready for Service date of 2027. The system is not yet operational at this time.

Regional Context

The eastern Baltic corridor served by Mjolner East is home to several other submarine cable systems. Established systems in the region include STO-HEL-One, connecting Finland and Sweden since 2008, and BCS North - Phase 1, which has linked Finland and Sweden since 1998. C-Lion1, running 1,172 km with a 2016 RFS date, represents a longer-distance route in the Finland corridor. More recent additions include Aurora, ready for service in 2024, and the forthcoming N0r5ke Viking 2, planned for 2028. At 450 km, Mjolner East sits within the mid-range length profile for cables in this area and, upon completion in 2027, will add another route connecting all three Baltic rim countries — Estonia, Finland, and Sweden — within a single system.

Strategic Role

By landing at four distinct points across Estonia, Finland, and Sweden, Mjolner East provides direct submarine connectivity linking the Estonian coast and capital with Helsinki and the Swedish island of Gotland. The four-landing configuration across three countries supports intra-Baltic connectivity for a region where demand for diverse routing options continues to grow. GlobalConnect's sole ownership positions the cable as a dedicated infrastructure asset within the company's northern European network.
