Detecting tunneling activity under the security fence separating Gaza from Egypt could be accomplished through a buried fiber-optic cable, according to researchers at the Technion-Israel Institute of Technology (Haifa, Israel). By combining a neural network with Brillouin optical time-domain reflectometry, small tunnels can be sensed by the buried optical fibers, researchers claimed.
