Bouygues Telecom has signed a deal to start providing a FTTH service in partnership with Altitude Infrastructure.
The operator will lean on Altitude to offer the pure fibre technology to both retail and business customers across France.
Self-styled alt-net Altitude has been working with local authorities to build, develop, operate and market alternative networks since 2001.
The France-based company specialises in Public Initiative Networks (PINs), which are deployed when no operator wishes to invest in building infrastructure on its own.
PINs are backed by public money and must get approval from local and European regulators where appropriate.
Altitude has passed one million premises with FTTH in 19 PINs across France.
The deal with Bouygues covers all the PINs, although it will focus on two in the east of France that represent 670,000 customers initially.
The two companies will begin a trial phase this September, with Altitude set to market the new services in 2018.
Bouygues had 3.1 million fixed broadband customers at end of December 2016, of which just 121,000 were signed up to FTTH.
Richard Viel, Deputy Chief Executive Officer of Bouygues Telecom, said: “Bouygues Telecom has already been a customer of Altitude Infrastructure’s networks for its business clientele for a number of years.
“This new partnership is further proof of our ambitions in FTTH, namely to be present in all of France’s PIN.
“These PIN will enable Bouygues Telecom to reach its target of 20 million premises marketed by 2022.”
In total, there were 3.2 million FTTH subscribers in France at the end of September last year across all of the country’s operators.
