Companies like the Montana-based Adelos have been developing their own versions of [fiber optic sensing] technology, and say the same fiber that could secure the border can also be used for telecommunications - and even provide broadband internet access to communities that live nearby.
“What we're doing is we're taking sound that is caused by things in the sky, on the ground, or subsurface - we're converting those sound waves, that pressure, and we're measuring how it impacts light in the cable itself, the fiber optic glass, and then we can convert that into acoustic information," Adelos founder and chief technology officer Alex Philp told INSIDER. "You can hear all this stuff happening. Sometimes it takes technology awhile to get into the public consciousness. Remember when it was weird to talk about fiber to the home? Well it's weird to talk about fiber as a sensor," Philp said. "I would argue that we are now at a tipping point in terms of understanding and adoption."
