SYNDICAT MIXTE DOUBS TRES HAUT DEBIT

What SYNDICAT MIXTE DOUBS TRES HAUT DEBIT does

Syndicat Mixte Doubs Très Haut Débit is a French public territorial consortium (établissement public de coopération intercommunale) established by decree in February 2013 at the initiative of the Department of Doubs and the 17 communautés de communes and agglomerations of Doubs. It is the aménagement numérique of the Doubs department, holding sole public-initiative competence over approximately 80% of the department's surface area, with the mission of bringing fiber-optic connectivity to every home and business in 485 communes. The Syndicate owns the public Dioptic Fibre network, a GPON/XGPON FTTH infrastructure comprising 46 NRO (Nœud de Raccordement Optique) central offices, 50+ SRO (Sous-Répartiteur Optique) distribution points, over 5,000 km of cables, and 131,026 FTTH lines, supplemented by 15,000 improved ADSL lines and the secondary PASSERELLE network.

The network is operated under a 14-year delegated service public (DSP affermage) contract with Altitude Infra, running from September 2021 to early 2036, under which Altitude Infra commercialises wholesale access to commercial ISPs (Bouygues Telecom, Free, Orange, SFR) who serve end customers, coordinates subscriber connections, and maintains the infrastructure. End-customer pricing is set by the commercial ISPs, not the Syndicate. The Dioptic platform also supports an FTTE (Fiber to the Enterprise) program with 4.5 million EUR dedicated investment, a Franco-Swiss cross-border interconnection via the Jougne-Pontarlier-Vallorbe route, and an enterprise connectivity offer managed by COVAGE on quality-of-service tiers.

The Syndicate's revenue sources are mixed public financing: contributions from the Department of Doubs and the 17 EPCI members, state and regional subsidies under the Plan France Très Haut Débit, bank loans (64.5 million EUR from Banque des Territoires, Banque Postale, and Caisse d'Epargne, against a total project cost of 190-200 million EUR over 10 years), and commercial network revenues collected through the DSP. The organization is governed by elected officials, with Denis Leroux (Vice-president of the Departmental Council) re-elected President in May 2026, and operates with a small administrative staff of six employees headquartered in Valdahon. Total project investment of 190 million EUR was completed in 2022, achieving 100% fiber coverage three years ahead of the national 2025 target.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Bouygues Telecom: National ISP that commercializes fiber services over the Dioptic network in Doubs. Comparable as a channel customer and as a builder of its own FTTH footprint in higher-density zones, with potential overlap in adjacent geographies.
• Orange: France's incumbent telecom operator and largest fiber ISP, which both competes in private FTTH zones and acts as a channel partner on the Doubs public network. Comparable as the dominant player in the broader French fixed broadband market.
• Free (Iliad): National ISP commercializing fiber over the Dioptic network and one of the most aggressive FTTH builders in France. Comparable both as a commercial channel for the public network and as a competing private fiber footprint operator.
• SFR (Altice France): National fiber ISP active on the Doubs network and a major private FTTH deployer in AMII zones. Comparable as a channel partner for the public network and as a competing infrastructure owner in neighboring territories.

Direct peers

• Covage: Wholesale fiber operator that animates the professional connectivity market on the Dioptic network in Doubs. Comparable as a French wholesale-only fiber infrastructure provider serving ISPs and enterprises across multiple regional networks.
• Altitude Infrastructure: Operates the DSP affermage contract for the Syndicat Mixte Doubs Très Haut Débit through 2036, and runs comparable delegated public fiber networks in many other French departments. Most directly comparable as the operating partner and counterparty for this and similar RIP projects.
• Axione: French public-initiative fiber network operator (Bouygues Construction subsidiary) deploying and operating FTTH networks for numerous départements and Syndicats Mixtes under similar DSP frameworks. Directly comparable in business model and customer base.

Regional players

• Syane / Haute-Savoie Numérique: Public energy and digital syndicat in Haute-Savoie operating a delegated FTTH network under a model very similar to Doubs THD. Comparable as a local-authority fiber owner monetizing wholesale access to ISPs across an alpine, low-density territory.
• Vendée Numérique: Public syndicate that built and operates the FTTH network in the Vendée department using a comparable public-investment + delegated-operation model. Comparable in mission, scale, and rural-urban mix, though geographically separate.
• Losange (Région Grand Est THD): Public-initiative FTTH network covering the Grand Est region under a similar Syndicat/Régie model. Closely comparable as a publicly-owned rural fiber network with delegated operations, but operating in a different French region.
