PRODUCTS
Three product lines — distributed acoustic sensing (DAS), BOTDA Brillouin analyzers and high-speed distributed acquisition cards — fully self-controlled from core boards to portable instruments.
Portable and rack-mount instruments: the DAS acoustic sensing instrument reaches 110 km at 5.8 kg, while the BOTDA Brillouin analyzer reaches 104 km with ±1 °C and ±20 με accuracy. Fibre in, results out — no external optics to align.
DAS-22-80KM
DAS-22-80KM is a portable distributed acoustic sensing instrument with up to 110 km single-channel range, 3–26 m spatial resolution, 0.01 Hz–100 kHz frequency response, 5.8 kg weight and 33–55 W power consumption, supporting polarization, spatial and frequency diversity reception with coherent-fading suppression.
