CityFibre has kicked off the roll-out of dense full-fibre networks in business parks across its 40 city UK footprint to reach more than 500 business parks.
The first parks targeted for upgrade are in the company's Gigabit City projects Coventry, Bristol and Peterborough.
The full fibre networks will be made available to ISPs and resellers on a wholesale basis.
Pre-registration rates of over 60% have been recorded in many of the business parks surveyed on the current footprint.
Greg Mesch, Chief Executive of CityFibre, commented: "This is preparing our cities for an inevitable future upgrade to Fibre to the Home."
Minister of State for Digital and Culture Matt Hancock said: "Fibre is the future. It will give small businesses across the country access to fast and reliable broadband and encourage other emerging providers to scale up so we remain a world-leading economy."
