E-FINEST

Overview

E-FINEST is a submarine cable system connecting Finland and Estonia across the Gulf of Finland. Commissioned in 2019, it is owned and operated by Elisa Corporation, a Finnish telecommunications company. The cable links Espoo, Finland, with Tallinn, Estonia, providing a direct and dedicated connection between the two neighboring Baltic Sea nations. Despite its relatively short length, E-FINEST plays a strategic role in enhancing connectivity and supporting data traffic in this high-demand regional corridor.

The Gulf of Finland is a critical maritime route and a hub for submarine cables due to its proximity to major urban centers and its role in linking Northern and Eastern Europe. E-FINEST is one of several cables that cross this body of water, contributing to the robust telecommunications infrastructure between Finland and Estonia.

Route and Landings

E-FINEST spans the Gulf of Finland, a narrow arm of the Baltic Sea separating southern Finland and northern Estonia. On the Finnish side, the cable lands in Espoo, a city located just west of Helsinki. Espoo is part of the Helsinki metropolitan area and is known for its advanced technological and digital infrastructure, making it a logical landing point for a high-capacity submarine cable.

In Estonia, the cable terminates in Tallinn, the country's capital and largest city. Tallinn is situated on the southern shore of the Gulf of Finland and serves as Estonia's primary hub for international connectivity. The city's strategic location and established telecommunications infrastructure make it an ideal endpoint for E-FINEST. The cable's route across the Gulf of Finland is relatively short, reflecting the close geographic and economic ties between the two countries.

Ownership and History

E-FINEST is wholly owned and operated by Elisa Corporation, a Finnish company specializing in telecommunications and digital services. Elisa has a significant presence in both Finland and Estonia, making it a natural operator for a cable system that directly links the two nations. The cable became ready for service in 2019 and has been operational since then, providing a reliable and high-speed connection across the Gulf of Finland.

Elisa's ownership of E-FINEST allows for streamlined management and integration with the company's broader network infrastructure. This single-ownership model ensures that the cable operates efficiently and meets the growing demand for data transmission between Finland and Estonia. The cable's deployment reflects Elisa's commitment to enhancing cross-border connectivity in the Baltic region.

What Our Measurements Show

Our live monitoring of E-FINEST reveals consistent performance metrics that align with the cable's short geographic span. Over 167 measured corridors, the best recorded round-trip time (RTT) is 9 milliseconds, while the average RTT is 29 milliseconds. These figures highlight the efficiency of the cable in facilitating low-latency communication between Espoo and Tallinn.

The Gulf of Finland's narrow width and the cable's direct route contribute to its low latency, making it a valuable asset for real-time data applications and high-speed internet services. The cable's performance underscores its importance in the regional telecommunications landscape, where reliable and fast connectivity is essential for both personal and business communications. E-FINEST's operational metrics demonstrate its role as a key infrastructure component in the Estonia-Finland corridor.
