Longhaul network

Dark Fibre Europe

Thanks to our preferred suppliers BT, ProRail, GasLINE, NGN, TenneT, Energinet and our partner networks, Relined’s Dark Fiber network comprises 50,825 kilometres of fibre-optic cables. Over 13,825 kilometres in the Netherlands, 32,000 in Germany and 5,500 in Denmark. As a result, we offer complete coverage in these countries. This means that we can set up connections to almost any location.

We provide reliable long-distance connections and have finely meshed networks in various city centres. Many data centres and office buildings are connected to those networks.

We also offer offshore connections, for example, between the Netherlands and Denmark and between Denmark and Norway

Longhaul network – dark fibre in Europe

The Netherlands

Relined provides network capacity throughout the Netherlands. We offer a high degree of network density and are extremely well represented in ten city centres in the Netherlands, including Rotterdam, The Hague, Utrecht, Eindhoven, Groningen and Amsterdam where we even have our own metro network , to which almost every carrier-neutral data centre is redundantly connected. From the Netherlands we have interconnection points at various strategic locations with our networks in neighbouring countries, including an offshore cable to Denmark, various nodes to Germany and we also offer connection possibilities towards the UK and Belgium.


The Dark Fiber network in Germany also offers nationwide coverage. This allows us to set up long-distance connections to link urban centres. And a finely meshed Dark Fiber network is available within the city centres, to which many offices and data centres are connected. In Germany, we also have our own metro network in Frankfurt,one of the most important Internet hubs in the world. If you want to set up a network to a neighbouring country, we can link your connection to a network in one of the neighbouring countries, such as the link to our Danish network from Rostock.


In Denmark, we have access to a nationwide network with many interconnection possibilities. Our offshore network between the Netherlands and Denmark, the COBRA Fiber Optic Cable, offers you a reliable and fast connection between the Netherlands and Scandinavia. From Denmark you can also use one of our offshore cables to Norway and Sweden.
