How to Implement Your Own DAS System？

We provide different solutions for different customers.

Enterprise-Level Customers

Enterprise customers typically need complete products, including both hardware and software systems. For this scenario, we recommend our DAS all‑in‑one product, because all hardware has been integrated – just connect the fiber optic cable and start using it. Customers can focus solely on software algorithms for their specific application scenarios. We offer the following all‑in‑one configurations:

DAS All‑in‑One

• General‑purpose DAS all‑in‑one
  Except for the sensing fiber laid on site, all hardware is integrated into a 3U chassis. The user only needs to purchase a fiber optic cable, then can focus on software development for the sensing system. A demo software is provided.

• Enhanced DAS all‑in‑one
  

  Achieves higher spatial resolution than the general‑purpose model (3 m spatial resolution). Real‑time phase demodulation for all channels along the entire fiber. Built‑in coherent fading suppression algorithm. Outputs demodulated phase signals directly. Equipped with a GPU card, suitable for running AI algorithms directly.

• RtDAS high‑performance chirped DAS all‑in‑one
  Chirped swept‑frequency DAS uses a swept optical frequency rather than coherent single pulses. Combined with suitable demodulation algorithms, it effectively improves spatial resolution, system SNR, and sensitivity. Currently achieves 2 m spatial resolution, delivering outstanding performance in specific DAS application scenarios. The chirped DAS is also more responsive, making it very suitable for weak vibration sensing applications.

• Enterprise Customers Who Need to Build Their Own Chassis

• For enterprise customers who want to assemble their own DAS equipment chassis, they can use our integrated DAS modules and acquisition cards. We offer conventional DAS modules, enhanced DAS modules, as well as PCIe, Ethernet/optical interface data acquisition cards. Users can select according to their needs.

• DAS Modules

• Coherent fading suppression DAS all‑fiber demodulation module
  Deeply integrates the DAS optical acquisition front‑end with the high‑speed DAS data processing back‑end. Dimensions are only half an A4 sheet, providing a compact and convenient solution for distributed fiber‑optic acoustic sensing.

• DAS integrated module with 3 m spatial resolution
  Achieves 20 ns pulse width output, measured spatial resolution of 3 m, monitoring distance of 10 km. Specifically designed for belt conveyor roller monitoring applications.

• Conventional DAS integrated module with 6 m spatial resolution
  Integrates high‑performance 3 kHz narrow linewidth laser, AOM acousto‑optic modulator, EDFA amplifier, etc. Uses coherent detection optical path with very high sensitivity.

• Conventional DAS integrated module (with 200 MHz AOM)
  Integrated high‑performance 3 kHz narrow linewidth laser, AOM, EDFA amplifier, etc. Coherent detection path, very sensitive.

Acquisition Cards

• GY‑DAQ‑2510D 1 GSa/s dual‑channel high‑speed DAS demodulation card
  Dual‑channel 14‑bit high‑speed ADC, supports dual‑channel 1 GSa/s synchronous trigger sampling, supports DAS data acquisition up to >100 km. Built‑in phase demodulation algorithm; directly uploads amplitude and phase demodulated data. The phase data can be used directly as vibration signals without further demodulation processing, achieving full‑fiber demodulation.

• Ethernet / optical‑interface dedicated DAS data acquisition card (250 MSa/s), built‑in demodulation algorithm, coherent fading suppression
  Uses Gigabit Ethernet for data output. Built‑in distributed fiber sensing DAS demodulation algorithm with coherent fading suppression. Supports up to 50 km fiber demodulation at 1.6 m spatial resolution. When paired with our DAS modules, enables a compact, portable, low‑power DAS system.

Research‑Level Customers

Research customers often need to understand the internal working principles and components of a DAS system, and may require modifications to the DAS optical path. We offer a separate hardware module solution for DAS systems. A BOM (Bill of Materials) is provided.
