AP Sensing’s DTS is based on the Raman Optical Time Domain Reflectometry technology (R-OTDR). AP Sensing uses its patented code correlation OTDR (CCOTDR) that allows the utilization of low optical power. It eliminates any problems with laser degradation and enables worry-free, long-term measurement stability. CC-OTDR technology also offers the advantage of a large optical budget, which is crucial for long-range installations having long lead fibers and short-range systems with high loss.
