France reaches 94.9% fiber coverage in 2026

France achieved a remarkable 94.9% fiber coverage in 2026, according to data released by the Autorité de régulation des communications électroniques et des postes (ARCEP). The data, which is open and published under the CC-BY-SA license, was compiled from declarations made by operators by December 31, 2025.

The interactive map, available on the ARCEP website, allows users to visualize the rollout of fiber networks (FttH) across the country. The map is divided into two levels of detail: a communal level and a technical level (generally infracomunale). It provides a comprehensive view of the progress made in bringing high-speed internet to every corner of the nation.

Four additional views can be accessed in advanced mode, offering deeper insights into the deployment process. These include detailed operator data on fiber deployments, aggregated data at the commune level, and information on mutualization points (PM) and their ZAPM (zone arrière de point de mutualisation) areas. The map also highlights the current state of deployment for each address, with varying colors indicating the progress of the rollout.

While the data is generally reliable, it's important to note that in some densely populated areas, access to fiber networks may be accessed directly from buildings rather than through mutualization points. In such cases, the map uses an intermediate level of detail for these infra-comunale areas, represented by "IRIS" zones defined by INSEE.
