GNM Expands European Optical Transport Network to Enhance Connectivity and Resilience
GNM recently completed a major expansion of its European optical transport network, extending its dense wavelength division multiplexing (DWDM) backbone from Sweden to the Balkans. This expansion introduces new diverse routes aimed at improving regional connectivity and operational resilience.
Modernization of Frankfurt–Kista Corridor
As part of the upgrade, GNM modernized the Frankfurt–Kista corridor by refreshing its Kista node with comprehensive hardware and rack-level updates. This enhancement not only increases available bandwidth but also reduces energy consumption and enhances overall efficiency in Northern Europe.
New DWDM Line Connecting Bratislava to Sofia
GNM also launched a new DWDM line connecting Bratislava to Sofia through two distinct paths – one passing through Belgrade, Serbia’s capital, and the other through Romania. These routes converge in Sofia, creating a scalable, high-capacity North-Southeast corridor. This strategic positioning of Sofia as a critical interconnection point benefits traffic from the Balkans, Turkey, and the Middle East.
Strategic Importance of the Upgrade
Alex Surkov, GNM’s Head of Development, emphasized the strategic significance of the network expansion. He stated, “We’re strengthening the backbone for regional transit and future growth by connecting Northern and Southeastern Europe through diverse, high-capacity links.”
The expansion addresses the increasing demand from regional carriers, content delivery networks, and digital platform providers for low-latency, high-availability infrastructure across Europe.
