DELTA Fiber and Open Dutch Fiber are pleased to announce that they will be working together. Under this agreement, DELTA will for the first time offer its telecom services to consumers over the fiber network of another network owner. As a result, households connected to the Open Dutch Fiber network will gain access to DELTA’s internet, television and phone services.

The partnership starts with more than 200,000 addresses on the Open Dutch Fiber network. These are addresses in a range of municipalities, including Sittard-Geleen, Roosendaal, Venlo, Woerden and Kerkrade. In a single step, this significantly expands DELTA Fiber’s reach. At the end of this year, DELTA will announce which subscriptions will become available at these addresses. Service starts early next year. The agreement also creates opportunities to expand that reach further in the years ahead.

Greater freedom of choice

The fiber networks of Open Dutch Fiber and DELTA Fiber are located in different areas and complement each other well geographically. Both companies have chosen to make smart use of existing networks. This gives more households access to DELTA’s offering, while residents on Open Dutch Fiber’s open network can choose from a wider range of providers and services.

Paul Naastepad, CEO Open Dutch Fiber: “This partnership shows how the Dutch fiber market continues to develop. Building multiple fiber networks in the same area leads to high costs for society and lower utilization of existing infrastructure. We believe that cooperation between network companies is a logical and sustainable choice. It is precisely by opening up our networks to each other that we increase the reach of service providers. Ultimately, it is consumers who benefit most, through greater choice and more efficient use of the fiber infrastructure.”

For DELTA Fiber, the agreement marks a new phase. It is the first time the telecom company will deliver broadband services to consumers over a fiber network that it does not own and operate itself.

Stefan Fuchs, CEO DELTA Fiber: “This is an important milestone for us, both within our strategy and for our commercial positioning. For the first time, we are bringing DELTA’s offering to households outside our own network. DELTA has been named the fastest internet provider in the Netherlands for the fourth year in a row, and we are now bringing that quality to these new locations as well. This gives more than 200,000 households on the Open Dutch Fiber network the option of a quality provider that is proven fast and reliable, with the service that goes with it. That fits our ambition to keep growing in both customers and reach.”

Complementary networks, shared ambition

Open Dutch Fiber and DELTA Fiber share the conviction that fiber networks should be used as efficiently as possible. In a market where more and more households have a fiber connection, the focus is shifting from construction to making optimal use of existing infrastructure. Partnerships between network companies contribute to this.

By using each other’s infrastructure, they increase the availability of services, strengthen competition on service quality and give consumers more choice.
