What Fiber 31 does
Fibre 31 SAS is a French wholesale fiber optic network infrastructure operator headquartered in Toulouse, incorporated in 2018 as a joint venture between Altitude Infrastructure, Caisse des dépôts et consignations, and the MARGUERITE fund. The company was purpose-built to execute a 25-year Delegation of Public Service (DSP) contract awarded by Haute-Garonne Numérique, a public mixed syndicate created in 2016 by the Haute-Garonne Departmental Council. Its mission spans the full lifecycle of a public-initiative fiber network: conception, construction, operation, maintenance, and commercialization of passive FTTH (Fiber To The Home) and FTTE (Fiber To The Enterprise) infrastructure across the Haute-Garonne department.
The company's product surface is built on a passive optical architecture comprising Optical Network Termination (ONT) equipment, Dispositif de Terminaison Intérieure Optique (DTIO) units, Point Branchement Optique (PBO) nodes, and vertical building infrastructure (columnes montantes, goulottes). Network deployment was completed in four years (2018–2022), delivering 280,000+ planned connections covering 100% of Haute-Garonne Numérique's territory, with the network reaching 330,000+ marketable connections and 227,000+ subscribed households (69% penetration) by mid-2026. The firm is operationally embedded within the Altitude Infrastructure group (Altitude Infra), which following the 2021 acquisition of Covage became France's first national-scale independent fiber infrastructure operator with 5 million+ connections.
Fibre 31 monetizes exclusively through wholesale network access fees paid by Internet Service Providers under operator access contracts covering FTTH active/passive and FTTE passive lines. It does not sell subscriptions directly to end consumers; pricing to households is determined by individual ISP partners. The go-to-market combines a B2B channel-partner model (ISPs including Orange and other commercial operators) with direct engagement of local authorities through public information sessions ("permanences") in municipalities and a website-based eligibility testing tool. A wholly-owned subsidiary, Fibre 31 Déploiement, executes network construction. Customer segments are organized vertically: residential households (Particuliers), enterprises (Entreprises), local authorities (Élus et Collectivités), and ISP operators (Opérateurs).

Fiber 31 competitors and assessment
Company assessmentBroad incumbents
- Orange: France's largest telecom operator, a key ISP partner on Fibre 31's wholesale network and a major FTTH retail provider nationally — relevant as both a customer-counterparty and as a broader incumbent operating wholesale and retail broadband.
- Iliad / Free: French broadband operator with a fast-growing FTTH retail footprint that competes on wholesale networks like Fibre 31; relevant as both a potential ISP partner and a competing retail fiber provider.
- TDF: French infrastructure operator best known for broadcast towers but increasingly active in fiber and digital infrastructure; comparable as a regulated/wholesale-focused telecom-infrastructure platform serving multiple operators.
- Bouygues Telecom: Owner of Axione and a major retail FTTH operator in France; relevant both as parent of the most direct French FTTH peer and as a wholesale customer competing on DSP-built networks like Fibre 31.
- Altice France / SFR: Major French telecom operator combining retail broadband with wholesale-fiber interests via SFR Fibre; an important ISP partner and a comparable end-to-end carrier+ISP operator in the same value chain.
Direct peers
- Axione: Subsidiary of Bouygues Telecom operating as a wholesale FTTH/FTTE infrastructure operator under public-service models in France — the closest functional analogue to Fibre 31's DSP-driven wholesale fiber business.
- Covage: Former independent French wholesale fiber operator (consolidated within Altitude following the 2021 Covage asset acquisition); directly comparable business model of operating public/private FTTH/FTTE networks for ISPs.
- Altitude Infrastructure: Parent and lead operator of multiple French public-service fiber networks including Fibre 31; offers the same wholesale FTTH/FTTE model across many regional DSPs and shares technical and operational platforms with the subject.
Regional players
- Deutsche Glasfaser: Germany's largest independent FTTH wholesale operator deploying rural and semi-urban fiber under regulated/cooperative models; analogous in business model (wholesale infrastructure for ISPs) but operating in a different geography.
- Delta Fiber: Dutch fiber operator combining wholesale and retail FTTH across regional networks; comparable to Fibre 31 as a multi-ISP wholesale fiber platform focused on regional/town coverage outside major cities.
