Destruction of underground utilities in Texas has gotten so bad they're starting to implement automated, scifi-tier sensor technologies that leverage fiber optics.
> Texas811, the nonprofit organization that manages the state's "call before you dig" system, today announced the launch of Texas811 Guardian. The innovative technology uses distributed fiber-optic sensing to turn existing fiber-optic lines into real-time monitoring systems that detect excavation activity, preventing damage before it occurs.
> The sensitivity and speed of Rayleigh-based sensing allows distributed monitoring of acoustic signals over distances of more than 100 km from each laser source.
