The copper switch-off across Europe is already underway. In our previous blog about the copper switch-off tipping point, we described how many operators are already well into the transition from legacy copper to fiber. According to the FTTH Council Europe Copper Switch-Off Tracker, fiber’s share of incumbent access lines across Europe continues to rise as operators accelerate migration from copper networks. Norway and Spain have already completed the switch-off.
As the first wave of migration continues, the question is no longer why fiber is needed but how to execute the transition efficiently at scale. The copper switch-off is a multi-year transformation that touches everything from network architecture to customer migration, quality of experience, and device lifecycle management. Lessons from markets that are further along provide practical insights for operators now accelerating FTTH deployment.

1. Combine clear timelines with customer migration planning
One of the most effective tools for accelerating copper switch-off is a clear and predictable timeline. In markets such as the UK and Sweden, operators have released phased copper-shutdown schedules aligned with broader national digital strategies. These timelines allow customers, service providers, and regulators to prepare for the transition.
However, deadlines alone are not enough. Migration plans provide a proactive approach to mission-critical services and applications, including telecare systems, alarm services, and other critical infrastructure that have historically relied on copper voice lines. Dedicated migration programs, targeted testing, and fallback options reduce political risk and prevent delays during the switch-off process. For operators, the key lesson is that technical migration must be paired with customer transition planning.
2. Treat copper switch-off as a network transformation and prepare for long-term scalability with interoperability
Decommissioning copper networks provides an opportunity to redesign the access network for long-term scalability. Fiber networks are inherently simpler than legacy copper-based networks because passive optical network (PON) infrastructure eliminates active electronics from the field, lowering costs and energy use.
However, the real advantage of FTTH is its ability to evolve and scale. Technologies such as GPON and XGS-PON already support multi-gigabit broadband services and enable future upgrades without replacing the underlying infrastructure. Capacity can be scaled in line with demand rather than costly rebuilds.
To unlock this flexibility, networks must be designed with interoperability in mind from the start.

As FTTH deployments grow, operators rely on multi-vendor PON environments including OLTs, ONTs, and access devices. PON standards such as ITU-T and BBF.247 ensure interoperability, but in practice, the reality is often more complex due to proprietary devices, different OLT software versions, and network configurations. At Genexis, interoperability is a core design principle for our ONTs, which are seamlessly interoperable with any OLT, ensuring network efficiency and performance.
3. Focus on the fiber access edge
Fiber deployment usually focuses on backbone infrastructure. Yet one of the most critical parts of the copper-to-fiber transition occurs closer to the end user. In FTTH deployment, the termination point is a critical interface between the network and the end user, and the home is a digital hub as households rely on cloud services and AI applications.
Reliable, secure, and remotely managed termination points are vital for scaling FTTH deployments, as the number of connected devices increases dramatically. Managing these devices effectively becomes a central operational challenge. Interoperable OLTs and ONTs, lifecycle device management, firmware updates, security monitoring, and remote provisioning all contribute to maintaining network reliability and performance.
Automation and centralized device management tools like Genexis CloudSight help operators monitor millions of endpoints, simplify operations, and ensure service quality while lowering costs over time.
4. Leverage existing in-building copper in multi-dwelling units
One of the main practical challenges in copper switch-off programs happens in multi-dwelling units (MDUs), where 35% of the EU’s buildings are over 50 years old. Older MDUs use legacy in-building copper wiring, such as coax or twisted pair, that runs through dozens or hundreds of apartments, leading to significant deployment delays. Often, operators face logistical barriers like building access, installation costs, and disruptions to residents. As a result, the final step of switching from copper to fiber can become the most complex.
Our MDU solution, FiberBridge, allows operators to provide high-speed FTTH broadband services by reusing existing in-building cabling and connecting each apartment to fiber. This approach helps operators transition customers from copper networks more quickly and prepares buildings for future full-fiber connectivity. For operators managing large-scale copper switch-off programs, solutions that simplify in-building deployment can significantly speed up migration timelines and reduce installation complexity.

From fiber migration to network optimization
For many operators, the copper switch-off has shifted from a strategic decision to an operational necessity. The next stage emphasizes refining the deployment, activation, and optimization of FTTH networks. Operators that combine clear migration plans with interoperable PON architectures, intelligent access-edge management, and practical deployment strategies, such as leveraging existing in-building wiring, will be better positioned to accelerate the transition while maintaining service quality.
The copper era established the foundation for connectivity, but the fiber era is about building resilient, scalable infrastructure for the AI economy. Operators who see the copper switch-off as an opportunity to accelerate FTTH migration will ultimately turn this transition into a long-term competitive advantage.
