Applications and Research

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 further diversifies 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. This added diversity and geographical reach extends the value of the top-two ranked global backbone, AS1299.

As St. Petersburg and Moscow are important transit points for Asian traffic, the new route also allows Telia Carrier to service the increase in traffic coming into Europe from Asia via terrestrial cable routes from the East as well as directly from Russia.

The subsea cables reaching across the Baltic Sea have been upgraded using the latest 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.”
