What Unifiber does
Unifiber SA is a Belgian wholesale-only operator that designs, builds and operates an open-access passive fiber-to-the-home (FTTH) network across 61 municipalities in Wallonia. The company is a 100% subsidiary of Proximus, Belgium's largest telecom operator, and was established specifically to accelerate fiber deployment in medium-density areas where Proximus itself does not directly invest. Unifiber targets making 600,000 homes connectable to fiber by 2028 — roughly 10,000 km of fiber-optic cable backed by a near-€1 billion capital commitment from its parent over a 10-year horizon, with current deployment at 400,000+ connectable addresses and incremental roll-out of approximately 100,000 addresses per year as of 2024.
The core product is a passive, point-to-point FTTH infrastructure made available on a non-discriminatory basis to licensed telecom operators — including Proximus, VOO, Orange and others — who then resell internet, telephony and TV services to end users. The network supports symmetric speeds up to 10 Gbps, is engineered for roughly a 50-year lifespan, and is positioned as approximately 4x more energy-efficient than legacy copper. End-customer connections are provided free of charge, with wholesale tariffs to operators regulated by Belgium's IBPT regulator. The portfolio also includes residential installation services (Homes Connect), multi-dwelling unit installation, and a self-service DIY conduit guide.
Unifiber generates revenue from recurring wholesale access fees. The B2C reference offer has received qualitative approval from IBPT with quantitative tariffs under review; the B2B offer remains pending regulatory clearance. Revenue figures are not publicly disclosed. The company employs a small executive team drawn from Proximus, Telenet, VOO and Elia, and operates from Waterloo, Belgium.

Product offeringCore offering
Unifiber designs, builds, operates and maintains an open-access passive Fiber-to-the-Home (FTTH) network across approximately 60-61 communes in Wallonia, Belgium. The company sells exclusively wholesale network access to licensed telecom operators on a regulated, non-discriminatory basis; end customers obtain internet, telephony and TV services through those operators. Physical fiber installation to homes and apartment buildings is performed by Unifiber (directly or via subcontractors) at no charge to end users.
Product overview
Unifiber is a management company focused exclusively on the design, construction, planning, operation, and maintenance of an open-access passive FTTH (Fiber-to-the-Home) fiber optic network in Wallonia, Belgium. It operates as a wholesale-only operator — it does not sell telecom services to end consumers. Instead, third-party telecom operators (such as Proximus, VOO, and Orange) subscribe to the Unifiber wholesale network to deliver consumer (B2C) and business (B2B) internet, phone, and TV services. The portfolio consists of the FTTH network infrastructure itself, two wholesale access products (B2C and B2B), residential fiber installation services (Homes Connect), apartment/multi-dwelling unit installation services, and a self-service DIY conduit installation guide for homeowners. End-customer fiber connections are provided free of charge. The company targets 600,000 connectable premises by 2028 across 61 municipalities, deploying over 10,000 km of fiber optic cable with an investment of approximately 1 billion euros.

Unifiber competitors and assessment
Company assessmentDirect peers
- Delta Fiber: Netherlands-based open-access fiber operator deploying FTTH wholesale networks across multiple regions and selling capacity to multiple ISPs, including its own retail brand — comparable in business model and European open-access fiber positioning to Unifiber.
- Open Dutch Fiber: Netherlands-based open-access FTTH wholesale operator (backed by KKR and Deutsche Telekom) building fiber networks that are made available to multiple ISPs — analogous in deploying large-scale open-access FTTH with institutional/wholesale-only economics.
- Netomnia: UK full-fiber wholesale network operator pursuing a multi-billion-pound FTTH rollout on an open-access basis — comparable business model (wholesale-only, infrastructure-led, multiple retail ISPs as customers) and similar scale of capital deployment as Unifiber.
- Deutsche Glasfaser: Germany's largest FTTH wholesale provider operating open-access fiber networks deployed in partnership with municipalities, with multiple ISPs reselling on the network — directly comparable to Unifiber in deploying municipal-authorized open-access FTTH for resale to multiple operators.
- SIRO: Irish wholesale-only FTTH operator (joint venture between Vodafone and ESB) deploying open-access fiber to 500,000+ premises that multiple Irish ISPs resell — a near-perfect model match for Unifiber's wholesale-only, multi-tenant, JV-funded fiber rollout.
- Glaspoort: Dutch open-access FTTH joint venture (KPN and APG) deploying wholesale fiber networks for resale to multiple ISPs in the Netherlands — closely mirrors Unifiber's parent-backed, open-access, wholesale-only positioning.
- CityFibre: UK-based wholesale-only FTTH infrastructure operator building open-access fiber networks that multiple ISPs (Vodafone, TalkTalk, etc.) use to serve end customers — the closest international analogue to Unifiber's wholesale-only, multi-tenant, municipality-authorized FTTH model.
Emerging players
- Community Fibre: London-focused FTTH operator deploying open-access-capable fiber primarily for retail ISPs and resellers — comparable technology and customer base (wholesale ISPs), though smaller and more retail-tilted than Unifiber.
Broad incumbents
- Proximus: Unifiber's 100% parent and Belgium's largest integrated telecom operator; both deploys fiber directly in major Walloon cities and is itself Unifiber's largest customer via the wholesale network — directly comparable FTTH deployment activity and Belgian telecom customer base.
Regional players
- VOO: Belgian cable and telecom operator (Wallonia-focused) that is both a customer of the Unifiber wholesale network and a competing infrastructure provider in adjacent regions — directly comparable in Wallonia-specific fiber/cable customer base and GTM motion.
