At DELTA Fiber, we believe fiber is the technology allowing you to get the most out of your internet connection. And we want to let as many people as possible benefit from this. We always go one step further. Since we started installing the fastest internet network in the Netherlands in the province of Zeeland more than twenty years ago, our passion and experience means we’ve grown into the country’s leading fiber expert. With the DELTA Network, we’re making lightning fast internet available to more and more people and companies, in more and more areas.
DELTA Fiber not only installs, but also provides the services on that fastest fiber network. With our brands DELTA and Caiway we provide gigabit internet, interactive television, telephony and mobile services. DELTA Fiber is owned by two investment companies: the Swedish EQT and the American Stonepeak. DELTA Fiber includes DELTA, Caiway, DELTA Network and ZeelandNet, with this joint company employing more than 1200 people.
