As demand for reliable, high-speed connectivity grows, fibre continues to expand across the OECD. Fibre now accounts for more than half (51%) of all fixed broadband subscriptions across the OECD, up from 31% in 2020. This shift is taking place in largely mature fixed broadband markets: OECD average fixed broadband penetration grew by only 2.2% per year in the last five years between 2020 and 2025, from 33 to 37 subscriptions per 100 inhabitants.
Fibre growth mainly reflects the migration of existing subscribers from legacy technologies such as DSL and cable.
Fibre adoption increased across all regions where OECD countries are present between 2020 and 2025, with particularly strong growth in Latin America, reflecting continued investment in high-capacity networks.
