What Thd Bretagne does

THD Bretagne is a wholesale public-initiative fiber network operator (opérateur d'infrastructures, RIP) that exploits and commercializes the public fiber optic network built across the four Breton departments (Côtes-d'Armor, Finistère, Ille-et-Vilaine, Morbihan) under a 20-year public service delegation granted by Mégalis Bretagne, the public mixed syndicate representing 59 Breton intercommunalités and the four departments. The company is a simplified joint-stock company (SAS) headquartered at 125 Boulevard Albert 1er in Rennes, with share capital of €3,440,000, and operates as a wholly-owned subsidiary of Orange Concessions within the Orange Group; Orange also provides industrial technical teams for 24/7 network operations and incident management. As of early 2026 the network covers more than 1.25 million eligible premises, with approximately 600,000 connected customers, ~697,000 active fiber subscriptions and a 55% take-up rate of eligible homes.

The network is a passive FTTH/FTTE architecture comprising Optical Nodes (NRO), Points of Mutualisation (PM), branch connection points (PB) and Optical Terminal Points (PTO), re-using existing copper conduit and aerial infrastructure where possible. THD Bretagne offers two core wholesale products: FTTH (Fiber To The Home), a shared passive fiber service marketed to ISPs for residential subscribers, and FTTE (Fiber To The Enterprise), a dedicated fiber service with guaranteed bandwidth, symmetric upload/download speeds and rapid fault restoration for businesses and public-sector organizations. An experimental deployment of rooftop photovoltaic panels and multi-sensor IoT units (power outage, door opening, smoke, temperature, humidity, video surveillance) is underway at four network shelter sites since December 2025, with surplus energy sold back to the local grid.

The business model is wholesale-only: THD Bretagne does not sell directly to end customers. Internet service providers (Orange, Bouygues Telecom, Free, SFR, Netensia, Xankom, and Orange Wholesale France for enterprise offers) subscribe to standardized reference offers (Accès Lignes FTTH, FTTE passif) and pay for network access, co-financing rights and contractual penalties. Demand generation is conducted primarily through community "Forum Fibre" events held across Breton municipalities (11 forums in 2025 assisting over 2,000 households), an interactive public eligibility mapping tool, and a state aid communication campaign for connection subsidies of €400, €800 or €1,200. End-customer pricing is set independently by each ISP. The general director is Olivier Feneyrol.

Revenue model

1. Network Access Licensing to ISPs: THD Bretagne, as the public infrastructure operator (RIP), grants internet service providers (Orange, Bouygues Telecom, Free, SFR, and others) the right to use its fiber optic network to serve end customers. ISPs pay for access to the passive fiber infrastructure. The company does not sell directly to end consumers; rather, it is the wholesale provider enabling ISPs to commercialize FTTH and FTTE subscriptions to households, businesses, and public sector entities across Brittany.

Core offering

THD Bretagne operates and commercializes the public fiber optic network built by Mégalis Bretagne across the Brittany region under a 20-year concession.
