Opinion: Updates on Distributed Fibre Sensing (DFS)

Updated the page on Distributed Fibre Sensing (DFS) with some inputs from an expert in the field . Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) are both pretty off the shelves products 🤓

Introduction 

DFS is the short form for distributed fibre sensing (or distributed fibre optics sensor). It is the ultra long sensing distance type of fiber optic sensors. Most of the time ordinary optical fiber (single mode fiber) may be used to sense for heat changes in existing infrastructure such as smart nation applications. Distributed Temperature Sensing (DTS) systems are the most commercial available DFS system in the market today. Their typical sensing spatial resolution is 1 meter with 1 degree Celsius accuracy in very ideal conditions. Wealthy end user such as those in oil and gas industry use Distributed Acoustic Sensing (DAS) system for acoustic sensing. In practical use cases, DAS are greatly affected by environment (wind, thunder, etc.) and human activities (machinery alike disturbance, false intrusion, etc.) if present.
