Who is Open Fiber?
Open Fiber S.p.A. is an Italian wholesale-only telecommunications operator focused on designing, building, and operating Fiber-to-the-Home (FTTH) and related ultra-broadband infrastructure.
- Nationwide FTTH and ultra-broadband network deployment for residential, business, and public sector connectivity (network infrastructure).
- Wholesale-only dark fiber and bitstream access services for retail telecommunications operators (wholesale connectivity).
- Network design, construction, and operation leveraging fiber optic technologies and Passive Optical Network (PON) architectures (telecom infrastructure services).
- Ultra-broadband solutions supporting smart city, public administration, and enterprise digitalization projects (enterprise and public sector connectivity).
- Open access infrastructure model enabling multiple service providers to deliver internet, voice, and data services over a shared fiber network (open access networking).

More About Open Fiber
Open Fiber S.p.A. develops and operates a nationwide fiber optic access network in Italy based on a wholesale-only, open access model. The company focuses on FTTH deployments, providing last-mile connectivity that retail service providers use to deliver high-speed internet, voice, and data services to households, enterprises, and public institutions. Its infrastructure is positioned as a utility-like asset that retail operators, system integrators, and public bodies can integrate into their own service portfolios without operating the underlying physical network.
The technical foundation of Open Fiber’s network is fiber optic technology, typically implemented using point-to-multipoint PON architectures for FTTH coverage, along with point-to-point fiber links where required. This architecture supports high bandwidth and low latency connections suitable for bandwidth-intensive enterprise workloads, cloud access, and real-time applications. The network extends from national backbones and metropolitan rings down to local distribution and customer premises, enabling end-to-end optical connectivity within Italy’s fixed access domain.
In the enterprise and institutional context, Open Fiber’s offerings are used as the physical access layer for a range of services provided by third-party operators. Enterprises may contract with their preferred service provider, which then consumes Open Fiber’s wholesale products, such as dark fiber (network infrastructure) or bitstream access (wholesale broadband), to reach office sites, industrial facilities, or distributed branches. Public administrations and utilities can also rely on the same infrastructure for e-government platforms, smart grid telemetry, and other digital public services, with the retail or integrator partner managing higher-layer services and security.
From a technology stack perspective, Open Fiber focuses on Layer 1 and Layer 2 capabilities, delivering optical and Ethernet-based access services that can be integrated into Multiprotocol Label Switching (MPLS), Software-Defined Wide Area Network (SD-WAN), Virtual Private Network (VPN), and cloud connectivity architectures managed by retail operators. The FTTH infrastructure is compatible with standard broadband and ultra-broadband protocols adopted by retail ISPs in Europe, enabling symmetrical or asymmetrical service profiles as defined by those ISPs. Compared with legacy copper or hybrid fiber-coax networks, FTTH infrastructure provides higher bandwidth ceilings and more predictable performance for enterprise workloads, though service definitions and Service Level Agreements (SLAs) are set by the retail provider rather than by Open Fiber directly.
Within an enterprise IT and telecom directory, Open Fiber is categorized under fixed network infrastructure, wholesale fiber connectivity, and FTTH access services. The company’s open access and wholesale-only positioning means it does not compete in the retail Internet Service Providers (ISP) space but instead supplies infrastructure capacity to telecom operators, over-the-top providers, and system integrators. For organizations planning network architectures in Italy, Open Fiber’s footprint, technical specifications, and wholesale access models are relevant when assessing last-mile options, fiber availability, and integration with multi-operator, multi-cloud connectivity strategies.
