Telia Carrier has established a new route stretching from Stockholm to St. Petersburg via Tallinn, and has upgraded multiple submarine cables to future proof its network, bringing lower latency and additional capacity.

The new route should further diversify the wholesale carrier’s network and the upgrade enables Telia Carrier to provide 100G+ services to carriers, content and cloud providers in the Baltics, Russia and beyond.

The new network extension is the most direct route possible from Stockholm to St. Petersburg at just under 900 km. With a connection in Tallinn, Estonia, Telia Carrier’s mesh network extends in different directions reaching multiple cities including Riga, Latvia or Helsinki, Finland.

The subsea cables reaching across the Baltic Sea have been upgraded using coherent Flex-Grid technology allowing Telia Carrier to offer 100G, and future 150G and 200G services leveraging the latest modulation formats.

“As our network becomes more meshed throughout Eastern Europe and the Baltics, we are continuing to build out eastward to stay ahead of content demand and the resulting backbone traffic in the region,” said Johan Godal, global product manager, wavelength and network outsourcing services at Telia Carrier. “By extending the route from Sweden to Russia and upgrading the submarine cables in the Baltic Sea, we can now offer high capacity and low latency services via a highly-meshed network throughout the region.”
