DTS & DAS

Overview

The DTS & DAS system leverages the inherent scattering properties of optical fibres to provide real-time, distributed monitoring of temperature, vibration, and acoustic signals over long distances.

• DTS (Distributed Temperature Sensing)

  Utilises Brillouin and Raman scattering to detect temperature variations with high accuracy along fibre optic cables.

• DAS (Distributed Acoustic Sensing)

  Converts existing optical fibres into thousands of virtual microphones, enabling detection of vibrations and acoustic events.

Together, DTS + DAS form a multi-parameter sensing solution that enhances the safety, reliability, and security of modern infrastructures.

Distributed Temperature and Acoustic Sensing (DTS & DAS) system uses standard fiber optic cables as sensors to form a powerful monitoring network. Delivering a scalable, cost-effective solution for improving the safety, reliability, and security of infrastructure through the use of existing fiber optic networks.
