tunnel fiber optic sensing

Austrian Federal Railway OeBB celebrated the final breakthrough on the Styrian side of the Semmering Base Tunnel

distributed fiber optic sensing has become more popular in tunneling applications….This paper introduces a novel sensing and evaluation concept, which combines DFOS strain measurements and geodetic displacement readings for distributed shape assessment along curved structures, such as tunnel

Eysturoy tunnel is the world’s second-longest underwater tunnel….AP Sensing’s fiber optic Linear Heat Detection Series (N4387B) is one of several advanced technologies included in the tunnel in order to ensure its safety.
