FTTH Conference 2026 – London | Building Resilient FTTH Networks

In London, Loïc Mahut, Director of International Development at Altitude Infra, also represented InfraNum – the federation bringing together all of France’s digital infrastructure players. He joined Neil McRae – CTIO, CityFibre (UK), Katja Kmet Vrcko – Co-Chair, Cybersecurity & Resilience Working Group, AKOS (Slovenia), Jaakko Wallenius – VP Resilience & Defense, Elisa (Finland), and Christian Laqué – CTO, A1 (Austria), in a session moderated by Neill Gallagher, Copenhagen Economics.

Loïc Mahut shared Altitude Infra’s vision and hands-on approach to FTTH network resilience, drawing on work carried out alongside InfraNum and the Banque des Territoires.

Our definition of resilience? The ability to withstand and absorb failures without significant service disruption, with rapid restoration,  whether full or partial.

In France, the rollout of 40 million connections in just 10 years, half of them in rural areas, has been nothing short of extraordinary. The vulnerability of aerial infrastructure to wind, fire, and flooding shouldn’t come as a surprise; it’s a reality we now need to address collectively. Burying 200,000 km of network would represent a €20 billion investment. The question isn’t whether we need to act, but when and where to prioritise.

That’s precisely why Altitude Infra has structured its action plan around 4 interdependent pillars, incident response, operational intelligence, service resilience, and physical robustness, underpinned by a 5-dimension vulnerability scoring model that allows us to prioritise actions region by region. Because every territory comes with its own risk profile.

Proud to carry the voice of France and its industry on the European stage.
