CityFibre is aiming to rollout full-fibre 1Gb broadband in 20 cities across the UK by 2016.
The infrastructure provider - which specialises in the deployment of fibre-to-the-premises connections - is aiming to reach one million homes.
CityFibre has already launched full-fibre broadband in locations such as Bournemouth, Peterborough and Coventry.
The firm also recently announced plans to build a 1Gb broadband network in York, which Sky and TalkTalk will use to deliver broadband deals.
Greg Mesch, Chief Executive Officer at CityFibre, said the company has a "strong capital base" which helps to support its expansion plans.
"We can now put our foot firmly on the pedal in our roll-out of Gigabit Cities," he stated.
"All the evidence points to the social and economic advantages enjoyed by cities with a future-proofed digital infrastructure."
Mr Mesch said his firm welcomes the increased interest from cities and their service providers in its shared fibre infrastructure solution.
He said pure fibre can help support economic growth in the UK, and ensure Britain remains competitive internationally as other nations upgrade their own connectivity.
