•FiberCop and Nokia trial lets existing fibre detect vibrations and ground movement
•Fibre infrastructure evolves from connectivity platform into operational intelligence tool
The fact
FiberCop and Nokia have completed a trial of distributed fibre sensing technology on FiberCop's access network in Italy, enabling existing fibre-optic cables to detect vibrations, ground movement and other environmental activity without dedicated field sensors. The trial demonstrated how the same infrastructure can deliver broadband services while supporting predictive maintenance.
The technology analyses changes in light travelling through optical fibre to identify physical events near the cable, including construction activity, ground movement and mechanical stress. Because the fibre itself acts as the sensing medium, operators can extend monitoring across existing networks without installing additional sensors. FiberCop's network passes more than 13 million premises across Italy, showing the scale at which existing fibre assets could provide operational visibility alongside communications.
The assessment
Fibre networks are taking on a broader operational role. For decades, their primary purpose was to transport information. Distributed sensing gives the network a second function: monitoring the environment through which it already passes. That changes how operators maintain and protect critical infrastructure.
Continuous monitoring gives earlier visibility into construction activity, ground movement and other events that could disrupt services before faults occur. As networks grow larger, operational visibility matters as much as reach, enabling faster responses and better-informed maintenance decisions.
For BTW readers, predictive infrastructure management is becoming a competitive capability. Operators that use existing fibre networks to generate operational intelligence, rather than simply carry traffic, can improve resilience while cutting maintenance costs. Infrastructure that senses its environment is more valuable than infrastructure that only carries data.
What to watch
Watch whether operators move beyond trials into commercial deployment of fibre sensing. Adoption by utilities, transport operators and other critical infrastructure providers will indicate whether the technology becomes standard operational capability or remains a specialist application.
