DAS is currently widely used for monitoring of onshore pipelines including leak detection, external interference and ground movement monitoring.

DAS is also an attractive solution for perimeter intrusion detection targeted at the protection of critical assets in different market segments. With the long- range capability, it also provides an effective solution for border control.

By using existing optical cable networks in urban areas, DAS can provide sensing grids for high resolution traffic monitoring (including vehicle and road condition).

Railway monitoring is also an emerging application of DAS. With an optical cable along the track, DAS can provide information about moving trains, detect third party activity and locate rocks and landslide events.

The strong benefit of the OptoDAS interrogator for most of these applications is the low-noise characteristics and the high-power budget capability.
