"Fiber Optics: From Internet to Train Monitoring"
Originally Published 1 year ago — by Slashdot
Fiber optic cables, traditionally used for internet connectivity, are now being repurposed for distributed acoustic sensing (DAS) to monitor train activity and infrastructure along railways. By analyzing the vibrations created by trains and other disturbances, scientists can detect potential issues such as track cracks, rockslides, or faults in track alignment. This technology utilizes existing fiber optic infrastructure and can provide detailed insights into the health of railways, potentially preventing problems before they occur.
