Italian wholesale network operator Open Fiber has begun testing the first sections of its broadband networks which have been rolled out under government tenders to improve connectivity in so-called ‘white areas’. The telco says fibre-to-the-home (FTTH) infrastructure in four municipalities is being opened to third-party service provider partners for six months of testing. Open Fiber has begun work on deploying fibre networks in 900 municipalities, with that total expected to reach 1,000 by the end of this year. Press rumours are linking Open Fiber to a potential tie-up with incumbent fixed line operator Telecom Italia (TIM).
