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.
