GNM has completed a significant upgrade of its European optical transport infrastructure, extending its high-capacity DWDM backbone from Sweden to the Balkans via fully diverse paths.
A major hardware and rack-level modernisation at GNM's Kista node finalises the Frankfurt'Kista corridor upgrade, increasing available bandwidth, reducing energy consumption, and improving operational efficiency in Northern Europe.
Concurrently, a new dual-path DWDM route has been launched between Bratislava and Sofia, with one path via Serbia (Belgrade) and another via Romania. The routes converge in Sofia, establishing a resilient and scalable North'Southeast optical corridor.
'By connecting Northern and Southeastern Europe through diverse, high-capacity links, we're strengthening the backbone for regional transit and future growth,' said Alex Surkov, Head of Development at GNM. 'Sofia's position as a regional hub makes it key for aggregating traffic from the Middle East, Turkey, and the Balkans'.
The expansion supports growing demand for low-latency, high-availability infrastructure across Europe, particularly from regional carriers, content networks, and platform providers.
