What Rosace does

Rosace (legal entity: SAS ROSACE) is a French regional fiber-optic infrastructure operator founded in April 2016 and headquartered in Entzheim, Alsace. The company was granted a Public Service Delegation (DSP) by Région Grand Est to design, build, and operate a neutral and open very-high-speed fiber network across 700 communes spanning the Bas-Rhin and Haut-Rhin departments. By October 2023, the network comprised 16,000 km of fiber optic cable, 47 Optical Connection Nodes (NROs), and 444,541+ commercializable connections, serving 250,000+ end subscribers. Rosace's parent company and principal shareholder is Altitude Infrastructure, a specialist in public-initiative fiber networks.

The company's core technology is a neutral, open-access FTTH/FTTO architecture — meaning Rosace does not sell subscriptions to end users. Instead, it provides physical layer infrastructure that 38+ Internet Service Providers (including Bouygues Telecom, SFR, Free, Orange, Adista, and regional specialists) use to deliver retail services. The platform combines fiber optic with 5G and LoRa connectivity within its GFU (Groupes Fermés d'Utilisateurs) secure-network offering for local governments, supporting applications such as video protection, public lighting management, and building supervision. Supporting tools include a fiber eligibility testing portal, a network speedtest, the "Grand Est Rosace" mobile/web application for municipal users, on-demand connection services for isolated premises, and the "Bus de la Fibre" mobile outreach vehicle.

Rosace generates revenue primarily through wholesale network access fees paid by ISP partners for use of the passive infrastructure, with additional managed-services revenue from FTTO enterprise lines and GFU contracts with local authorities. The business model is asset-heavy, capital-light on the operating side (11–50 employees), and structurally insulated by its exclusive DSP within Alsace. The company completed a project refinancing in July 2022 and continues territorial expansion, with the April 2024 integration of the Communauté de communes du Val d'Argent adding 5,623 connection points. Revenue figures are not publicly disclosed.

Broad incumbents

• TDF: French infrastructure operator managing telecom towers, fiber, and broadcast networks. Comparable as a wholesale-only infrastructure provider serving multiple operators, though focused more on broadcasting/towers than residential FTTH.
• Bouygues Telecom: One of the largest ISP partners on the Rosace network (FTTH and FTTO) and a national telecom operator with its own fiber infrastructure elsewhere. Comparable as both a wholesale customer of Rosace and a vertically integrated competitor in adjacent regions.
• Orange: France's incumbent telecom operator and historical copper network owner. Orange is both a partner ISP on the Rosace network and a competing fiber infrastructure operator in other regions, making it a broad incumbent that overlaps with Rosace across infrastructure and ISP layers.
• SFR (Altice France): Major French ISP and fiber operator, also a key partner ISP on the Rosace network (including SFR Business for FTTO). Comparable as both a wholesale customer of Rosace and a vertically integrated competitor with its own fiber footprint.

Direct peers

• Covage: Wholesale fiber infrastructure operator active across French regions under DSPs, now part of the Altitude Infrastructure group (same parent as Rosace). Highly comparable as an open-access wholesale fiber provider serving ISPs and public-sector clients.
• Axione: French open-access fiber infrastructure operator (subsidiary of Bouygues Construction) that builds and operates FTTH networks under public-service delegations across multiple French regions. Closely comparable business model to Rosace as a neutral wholesale fiber wholesaler serving ISPs.
• Altitude Infrastructure: Parent company and principal shareholder of Rosace, operating multiple delegated public fiber networks (DSPs) across France under the same open-access wholesale model. Directly comparable in business model, regulatory framework, and customer segments (ISPs and local governments).

Regional players

• Losange: Open-access fiber network operator covering the Grand Est region under a separate DSP, overlapping territorially with Rosace in Alsace's neighboring departments. Comparable business model (neutral wholesale FTTH) but operating in adjacent rather than identical geographic zones.
