About this network

Open Fiber is Italy's wholesale-only FTTH network operator, building fibre-to-the-home across the country and selling access to retail ISPs rather than to end users directly.

What it's used for

• Fibre home broadband in Italy: the physical FTTH access that consumer ISPs resell to households.

Notable

• An "eyeball" access network: addresses reached over this fibre are home connections, not servers, even though Open Fiber itself is a wholesale operator and not a retail brand.
• Owned by the Italian state investment arm (CDP) alongside institutional infrastructure investors; built as a competitor to the incumbent's copper/fibre network.

Interesting

• Part of Italy's national broadband plan to bring open-access fibre to smaller towns and rural "white areas" that retail carriers had left behind.
