Altitude Infra

Altitude Infra (formerly Altitude Infrastructure) is a French telecommunications infrastructure company that designs, builds, operates and wholesales access to fibre-optic networks on behalf of local authorities. It positions itself as an "opérateur d'infrastructure" dedicated to the Réseaux d'Initiative Publique (RIP) — public-initiative networks created to bring very-high-speed broadband to sparsely populated areas that major national operators have been slow to cover. The company works with local authorities and all stakeholders to meet the very-high-speed coverage challenge in low-density zones, in line with the national Plan France Très Haut Débit. Altitude Infra describes itself as a neutral wholesale operator: it does not sell directly to end users but offers a neutral service catalogue to service operators, who are then free to market their own offers to households, businesses and public institutions. Its activities span the construction of fibre networks under RIP and AMEL (Appel à Manifestation d'Engagements Locaux) programmes, the operation and maintenance of deployed networks, and wholesale commercialisation of access to internet service providers. The company reports more than 28 public-initiative networks, more than 5 million FTTH sockets under contract, more than 4.1 million FTTH sockets deployed and more than 1.6 million homes and businesses connected. It also states more than 20 years of experience, more than 900 employees, more than €5 billion of investments and 6,000 direct and indirect jobs. Altitude Infra is part of Groupe Altitude, described on its own website as an industrial operator and long-term investor founded in 1990, and as France's third-largest fibre-optic infrastructure operator and an expert in B2B telecoms. The group presents Altitude Infra as one of its subsidiaries serving businesses and territories. The brand operates across France through a network of regional public-initiative networks, including LA FIBRE 06, LOSANGE, EMERAUDE THD, COEUR COTE FLEURIE, CALVADOS, CORAI, DIOPTIC, FIBRE 31, PRISME, PIXL, MANCHE FIBRE, GRAND NANCY, REV@, RESOPTIC, GRAVELINES, DGL NETWORK, NUMERIQUE, OXYGENE, ROSACE, HAUTE SAVOIE, SOMME, Octogone, YCONIK, SEQUANTIC, SEINE ESSONNE THD and EUROP ESSONNE, among others. Its history includes a shift from enterprise and local-authority services into radio infrastructure such as WiMAX and microwave links in the 2000s, followed by a strategic move into fibre optics in 2009 as the national very-high-speed broadband programme created a growing market. In 2017 the company captured roughly a quarter of the public-initiative fibre network market, and in 2020 it acquired the infrastructure operator Kosc Telecom. In 2021 it acquired 26 fibre-optic networks from Covage, then part of the Altice group, bringing its number of operated fibre sockets to 5 million. Altitude Infra publishes corporate social responsibility reporting and is involved in regional digital-infrastructure initiatives, including private 5G projects such as the Dunkirk Grand Littoral roundtable in 2026.

Altitude Infra, formerly known as Altitude Infrastructure, is a French telecommunications infrastructure company. Its corporate history is intertwined with that of Groupe Altitude, which describes itself as having been founded in 1990 as an industrial operator and long-term investor. Wikipedia records that at its creation in 1995 the business operated in services to enterprises and local authorities. During the 2000s it deployed radio infrastructure such as WiMAX and microwave links, before pivoting in 2009 towards fibre optics, a market that became attractive thanks to the national very-high-speed broadband programme. The company itself states that it has been committed since 2001 to supporting public actors in implementing their digital development strategies, and that it is among the leaders in the French market. In 2017, Altitude Infra captured about a quarter of the public-initiative fibre-optic network market, representing nearly €110 million for very-high-speed broadband deployment in rural areas neglected by the major operators. In 2020, the company acquired the infrastructure operator Kosc Telecom for €14 million. In 2021, it acquired 26 fibre-optic networks from Covage, which belonged to the Altice group, bringing the number of fibre sockets it operated to 5 million. Altitude Infra's activities comprise the construction of fibre-optic networks in France under public-initiative network (RIP) and local commitment (AMEL) programmes; the operation and maintenance of deployed fibre-optic networks; and wholesale commercialisation of access to those networks to internet service providers. The company presents itself as a neutral operator that maintains impartiality and agility, welcoming any service operator with an attractive and diversified catalogue. It supports operators' sales forces through local commercial managers assigned to each network, a front-office service with operator relations, key account managers and pre-sales referents, and national supervision based in Normandy providing real-time monitoring and operation. By the mid-2020s, Altitude Infra reported more than 28 public-initiative networks, more than 5 million FTTH sockets under contract, more than 4.1 million FTTH sockets deployed and more than 1.6 million homes and businesses connected. It also reported more than 20 years of experience, more than 900 employees, more than €5 billion of investments and 6,000 direct and indirect jobs. The group positions Altitude Infra as France's third-largest fibre-optic infrastructure operator and an expert in B2B telecoms, playing a key role in the national very-high-speed broadband deployment strategy. The company continues to publish CSR reporting and to engage in regional digital-infrastructure initiatives, including private 5G projects.
