BCS North - Phase 2 is a short regional submarine cable system spanning 280 kilometres in the Baltic Sea corridor, connecting Finland and Russia. The system links the Finnish cities of Helsinki and Kotka with the Russian landing point of Logi, providing a submarine link between the two neighbouring countries.
In Finland, the cable lands at two points: Helsinki and Kotka. Helsinki serves as a major connectivity hub on Finland's southern coast, while Kotka lies further east along the Gulf of Finland.
In Russia, the cable lands at Logi, providing the eastern terminus of the system.
BCS North - Phase 2 is owned by Arelion, a wholesale network operator offering international carrier services. Arelion operates an extensive global network and has historically maintained significant infrastructure across the Northern European and Baltic region.
The cable was declared ready for service in 2000 and has been in operation since that year. It continues to function as an active submarine link between Finland and Russia.
BCS North - Phase 2 operates in a corridor that also includes C-Lion1, a 1,172-kilometre cable serving Finland that entered service in 2016, as well as the Kingisepp-Kaliningrad System (Baltika), which serves Russia and became operational in 2021. Compared to these later additions, BCS North - Phase 2 is a considerably shorter and older system at 280 kilometres, focused tightly on the Gulf of Finland crossing between Helsinki, Kotka, and Logi. Russia's connectivity portfolio also includes longer systems such as Polar Express, the Far East Submarine Cable System, and the Russia-Japan Cable Network, which serve entirely different geographic corridors.
Measured performance data from 291 ping tests over the past 60 days records an average round-trip latency of 97.4 milliseconds on this cable, with a best observed value of 8.6 milliseconds.
BCS North - Phase 2 provides a direct submarine connection between two Finnish coastal cities and a Russian landing station across a short stretch of the Gulf of Finland. With a total length of just 280 kilometres, the system is geographically compact and tightly focused on the bilateral Finland–Russia segment of the Baltic region's submarine cable landscape. Its two Finnish landings at Helsinki and Kotka offer a degree of geographic redundancy on the Finnish side of the link.
