Subsea fibre cables can 'listen out' for sabotage

Subsea fibre cables can 'listen out' for sabotage using fibre optic signals to listen out for surreptitious underwater drones.

Nato has launched a mission called " Baltic Sentry " to patrol the Baltic Sea with aircraft, warships and drones.

Noticing a temperature change along part of a buried cable could reveal that part has become unburied.

There is also "armoury wire", thick metal cords, running along the outer parts of the cable.

But should a vessel deliberately drag its heavy anchor across even a double-armoured cable, it will almost certainly still damage it.

While it is possible to bury cables in the seabed for additional protection, this might become prohibitively expensive over long distances.
