Quality of fibre optic networks

Arcep publishes a [** quarterly observatory** on the quality of fibre optic networks](https://www.arcep.fr/cartes-et-donnees/nos-publications-chiffrees/qualite-des-reseaux-ftth/derniers-chiffres.html). The data underlying this observatory, collected from commercial operators and fibre network infrastructure operators (FttH, Fiber to the Home), is published on this page. The data are published quarterly, in two csv files: — ‘ftth_qualite_reseau_AAAA_MM.csv’: indicators per network, on the perimeter of the network as a whole or of the department, averages calculated over the last six months until the last day of the month indicated in the file name — ‘ftth_qualite_historical_mm_YYY_MM.csv’: monthly history of indicators at the network parent company’s mesh, from January 2022 to the month indicated in the file name.
