Open Fiber

What Open Fiber does

Open Fiber S.p.A. is an Italian wholesale-only fiber optic network operator founded in 2015 and headquartered in Milan. The company builds and operates a national FTTH (Fiber To The Home) passive infrastructure using GPON and XGS-PON technology, with experimental 50G-PON and multicore fiber deployments in progress. As of April 2026, its network spans 168,037 kilometers of fiber, reaches 6,341 municipalities, and connects 17.428 million property units (20.2 million total homes including FWA coverage), serving 4.283 million retail customers indirectly through more than 300 licensed telecom operator partners including TIM, Vodafone, Wind Tre, Fastweb, Sky Italia, Iliad, PostePay, and Aruba.

The company operates under a strict wholesale-only model and does not sell directly to end consumers; instead, it provides neutral open-access infrastructure to Italian and international ISPs who retail services ranging from 1 Gbps to 10 Gbps symmetric connections. Revenue is generated through recurring subscription-based wholesale access fees paid by operator partners for use of passive infrastructure (fiber cables, ducts, cabinets) and active services. The product portfolio extends beyond core fiber to include a national xPoP Backbone (800 Gbps capacity with 64 Tbps long-distance record transmission), Edge Data Centers, an IoT Platform, Digital Twin (Realcity) urban planning tools, and smart-city solutions. Strategic partnerships span Nokia for network equipment, Cisco for public-sector digital transformation, ENEA and INGV for seismic monitoring applications (Progetto ATENA, Sensing Net), Acea and Autostrade per l'Italia for infrastructure-sharing, and Infratel Italia for government-subsidized deployments in 'Aree Bianche' (white areas).

Open Fiber is majority-owned by CDP Equity (60%), the state development bank, and Macquarie Asset Management (40%) following Enel's €2.65 billion divestiture in August 2021 at a €5.3 billion enterprise valuation. The Board has approved an €11 billion industrial plan supported by €4.1 billion+ in project financing, executing the PNRR-funded Piano Italia a 1 Giga rollout to close Italy's digital divide across urban centers and rural white areas.

Expansion highlights6 records

Direct peers

• FiberCop: FiberCop is Italy's secondary wholesale fiber network, majority owned by TIM (with KKR infrastructure investment). It is the most direct domestic competitor to Open Fiber, building parallel FTTH infrastructure and serving overlapping ISP customers across Italian municipalities.
• CityFibre: UK-based wholesale-only full-fiber operator backed by Goldman Sachs, Mubadala, and others. Operates the same wholesale-only open-access FTTH model as Open Fiber, selling capacity to ISPs and competing in last-mile fiber build-out at scale.
• SIRO: Irish wholesale-only FTTH operator joint venture between Vodafone Ireland and ESB. Operates an identical wholesale-only, open-access fiber model to Open Fiber, deploying FTTH in regional and rural Irish towns on behalf of multiple ISPs.
• Deutsche Glasfaser: Germany's leading alternative fiber-to-the-home wholesale and retail provider, backed by KKR. Closely comparable to Open Fiber in deploying FTTH in underserved areas and offering open access to multiple ISPs.
• Open Dutch Fiber: Dutch wholesale-only FTTH operator building fiber networks and providing open access to ISPs across the Netherlands. Operates a structurally similar wholesale-only model focused on suburban and regional fiber rollout.

Broad incumbents

• Liberty Networks & Infrastructure: Liberty Global operates large-scale wholesale and retail fiber/cable networks across Europe. As a broad incumbent, it offers comparable open-access and wholesale connectivity but operates at much larger geographic scale across multiple countries.
• BT Group (Openreach): Openreach is BT's wholesale fiber and copper access division serving the UK's ISPs under regulated open-access rules. Functions as the UK analog of Open Fiber's wholesale-only model but operates at much greater scale within a single national footprint.
• Orange Wholesale (France): Orange's wholesale and infrastructure division operates one of Europe's largest FTTH footprints and increasingly sells wholesale access to third-party ISPs in France. Comparable as a broad incumbent offering wholesale fiber, although Orange also competes at retail.

Emerging players

• Unifiber: Italian regional fiber wholesaler operating under the Piano Italia a 1 Giga concessions. Smaller and more geographically focused than Open Fiber but operates in the same wholesale FTTH space in selected Italian regions.
• FiberConnect: Italian fiber operator focused on enterprise and digital transition customers. Smaller and more enterprise-focused than Open Fiber, with some overlap in business fiber wholesale and connectivity services.
