One of the advantages of using fiber optic sensing for railway monitoring is that pre-existing trackside infrastructure and cables can be used, meaning the installation and maintenance of the system is low-effort and does not require trackside closures.
In comparison to other technologies that are traditionally used to monitor cable theft, DAS offers continuous sensing capabilities at every point along a track. Additionally, it is a smart solution and high performing technology. In combination with artificial intelligence (AI), DAS technology can be used for smart, predictive maintenance. The use of a digital twin – a digital representation of a train, railway track, or both – is used to optimize rail networks and provide better planning capabilities.
