TECHNICAL KNOWLEDGE LIBRARY
Understand the Technology. Select the Right Approach.
These guides explain how distributed fiber optic sensing technologies operate, how they compare with conventional monitoring systems, and where DTS, DAS, or integrated sensing may be applied.
02
Learn how DTS uses Raman backscatter for distributed temperature measurement and how DAS uses coherent Rayleigh backscatter for vibration and acoustic event detection.
03
Compare distributed and conventional perimeter security architectures across coverage, event localization, field infrastructure, analytics, scalability, and typical application fit.
04
A practical guide to selecting DTS for thermal risks, DAS for vibration and intrusion risks, or an integrated DTS and DAS architecture for combined monitoring requirements.
