NGN Fiber Network

What NGN Fiber Network does

NGN Fiber Network GmbH & Co. KG is a German dark fiber infrastructure provider headquartered in Aubstadt, Germany, operating one of Germany's largest privately owned fiber optic networks. As of December 2025, following the acquisition of netcon AG, the network spans more than 21,000 km of fiber infrastructure with metro coverage in Munich, Frankfurt, Berlin, Hamburg, Leipzig, Nuremberg, Erfurt, and Halle, connecting more than 180 data centers and more than 50 telehouses and POP sites, plus international connections to Belgium, France, Luxembourg, Austria, Poland, the Czech Republic, and the Netherlands via its parent Eurofiber Group's 76,000 km European footprint.

The company's core offering is Dark Fiber: unlit optical fiber strands leased to enterprise customers (carriers, mobile operators, financial institutions, government/municipalities, healthcare, retail, industry, transport/logistics, construction, education, and agriculture) who light the fiber with their own equipment, providing dedicated point-to-point, ring, cascade, or star network topologies on multi-year contracts. Supporting products include Connectivity services and full-service offerings covering network planning, civil engineering, installation, and ongoing operation. Underlying technology comprises G.652, G.652D, and G.655 quality fiber optic cables with an average fiber age of 5 years, laid at 1.2 m depth in segments up to 6 km long, monitored by a 24/7 Germany-based Network Operations Center with less than 0.1% reported network downtime. The company holds DIN EN ISO 9001:2015 and DIN EN ISO 14001:2015 certifications.

NGN operates as a privately held subsidiary of the Dutch Eurofiber Group, with revenue generated primarily through recurring dark fiber leasing subscriptions supplemented by professional services revenue from turnkey fiber construction and consulting. The go-to-market model is enterprise direct sales with custom contract-based quoting; there are no channel partners, no e-commerce, and no public pricing list. The company is led by CEO Christoph Völkel (appointed December 1, 2024, prior experience at Global Connect and Vodafone) and COO Arian de Korte, with an operational team of approximately 40–50 employees and a broader headcount of 101–250. Revenue figures are not publicly disclosed.

Direct peers

• euNetworks: euNetworks is a European wholesale bandwidth infrastructure provider owning and operating a dense fiber network across Western Europe, offering dark fiber and wavelength services to carriers, DCs, and enterprises. Its product mix, customer profile, and geographic overlap (Germany in particular) make it a very close direct competitor to NGN.
• Colt Technology Services: Colt operates an owned fiber network across Europe and Asia, providing dark fiber, Ethernet, and wavelength services to enterprises and carriers. Like NGN, it owns its infrastructure and serves similar enterprise verticals; however, Colt also offers managed lit services on top.
• 1&1 Versatel: 1&1 Versatel is a German fiber network operator focused on B2B connectivity for enterprise customers, with extensive metro and long-haul fiber in Germany. It competes with NGN for the same enterprise and carrier customer base, particularly in Germany's major cities.
• Deutsche Glasfaser: Deutsche Glasfaser is one of Germany's largest fiber-to-the-home/building operators and also offers wholesale fiber services. While it is more retail-heavy than NGN, it competes directly for fiber infrastructure customers and is a similar-sized private German fiber platform.
• GasLINE: GasLINE is Germany's other major dedicated dark fiber network operator, owned by regional and municipal utilities. Like NGN, it provides wholesale-only fiber infrastructure to carriers and enterprises across Germany — making it the closest direct comparable in terms of business model and customer base.
• Global Connect: Global Connect is a Northern European fiber infrastructure operator serving the Nordics, DACH, and Benelux — making it a geographic and product peer to NGN. Notably, NGN's new CEO Christoph Völkel previously served as Country CEO at Global Connect, highlighting the competitive proximity.

Broad incumbents

• Deutsche Telekom: Deutsche Telekom is Germany's dominant integrated telecom operator with the country's largest fiber footprint, selling dark fiber, lit services, mobile, and content. As a broad incumbent, it dwarfs NGN in scale but competes for the same dark fiber and enterprise connectivity business.
• Lumen Technologies: Lumen Technologies (formerly CenturyLink) operates one of the world's largest fiber networks, including significant European metro presence, and offers dark fiber, wavelength, and managed services. It overlaps with NGN at the wholesale and large enterprise layer across European geographies.
• Telefónica Germany (O2): Telefónica Germany operates a large fiber backbone supporting its O2 mobile and fixed network across Germany. While not a dedicated dark fiber wholesaler, it competes with NGN for enterprise connectivity and fiber backhaul demand from mobile network operators.
• Vodafone Deutschland: Vodafone Deutschland is an integrated carrier with a large German fiber footprint serving business and consumer customers. It competes with NGN for enterprise connectivity contracts and has historically been a target employer for NGN's leadership (CEO Völkel previously held a director role at Vodafone).
