• The trial will run in FiberCop's laboratories in Rome, evaluating vibration detection for fault monitoring.
  • Operators are turning buried fibre into a dual-purpose asset, adding sensing to connectivity.

The fact

FiberCop and Nokia announced on 8 July 2026 that they have signed a memorandum of understanding to trial distributed fibre sensing across FiberCop's optical network in Italy. FiberCop is Italy's largest wholesale fibre network operator, majority-owned by Telecom Italia (TIM), and manages the country's largest passive fibre infrastructure.

The companies will evaluate Nokia's Sensornet optical sensing technology in controlled environments, including FiberCop's laboratories in Rome, and across isolated fibre sections. The trial will assess applications including network monitoring and predictive maintenance. Nokia will supply its distributed acoustic sensing (DAS) platform, which sends laser pulses down optical fibre and analyses backscatter patterns to detect vibrations, pressure changes and temperature shifts along the cable.

FiberCop said the technology could reduce maintenance costs and speed up fault resolution by identifying problems before they cause outages.

The Assessment

The trial shows that telecom operators are beginning to view fibre networks as more than communications infrastructure. As networks mature, attention is shifting from expanding coverage to improving how existing infrastructure is operated and maintained.

Using existing fibre as a distributed sensor lets operators detect faults and external disturbances without deploying separate monitoring systems. The same buried cables carry traffic and report on their own condition, potentially cutting maintenance costs and speeding up response times.

For BTW readers, this points to a broader trend in internet infrastructure: fibre is no longer just a passive pipe. Operators are turning it into an active sensing platform that monitors network health in real time, making physical-layer visibility a standard capability alongside broadband delivery.

What to Watch

Watch whether distributed fibre sensing moves beyond trials into commercial deployment across European fibre networks, and whether other wholesale operators follow FiberCop's lead.
