Here are some of the key features that make the FSDSS-120 a standout digital storage solution:
The system operates on the principle of for vibration/acoustic detection, Distributed Temperature Sensing (DTS) for temperature profiling, and Distributed Strain Sensing (DSS) for strain/force measurement, all from the same fiber line. By leveraging coherent detection and frequency‑shifted interferometry , the FSDSS‑120 achieves high signal‑to‑noise ratio (SNR) even over the maximum range.
