Telia Carrier connects Stockholm to St. Petersburg, upgrades Baltic Sea submarine cable network

Fiber-optic network services provider Telia Carrier says it has opened a fiber-optic network route from Stockholm to St. Petersburg via Tallinn, Estonia. In support of the new link as well as its other infrastructure in the region, the service provider adds that it has upgraded several submarine cable networks as well.

Fiber-optic network services provider Telia Carrier says it has opened a fiber-optic network route from Stockholm to St. Petersburg via Tallinn, Estonia. In support of the new link as well as its other infrastructure in the region, the service provider adds that it has upgraded several submarine cable networks as well.

Telia carrier says the new route further diversifies its network, while the upgrade enables support of 100G+ services to carriers and content and cloud providers in the Baltics, Russia, and elsewhere.

Telia asserts the new fiber-optic cable route is the most direct from Stockholm to St. Petersburg, measuring just under 900 km. The company says its mesh network can now offer connections to such places as Tallinn, Riga in Latvia, and Helsinki. The new route also will enable Telia Carrier to support an expected increase in traffic coming into Europe from Asia via terrestrial cable routes from the East as well as directly from Russia.

Meanwhile, the undersea cable upgrades include the addition of coherent flex-grid technology. The enhancement enables Telia Carrier to offer 100-Gbps services as well as 150G and 200G services in the future.

"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."
