3 Hardware Configurations for Building Distributed Fiber DAS Systems

The system is built directly with our integrated DAS integration module and DAS data acquisition card.

Applicable users: Users focus on business domain knowledge, do signal data identification analysis, algorithms, don't want to spend too much energy on hardware development, want to realize distributed fiber optic vibration system at low cost for enterprise/university research labs, team with software programming capability.

Build steps.

• Buy distributed fiber optic vibration sensing system DVS/DAS integrated module
• Buy high-speed DAQ cards for distributed fiber optic vibration sensing systems
• Buy an IPC and power supply (you can use your own computer instead), which needs to support PCIE interface.
• Connect the sensing fiber optic cable and write software to do data processing on the computer according to your business area

Applicable users: university laboratories, graduate students of scientific research institutions and R&D departments of enterprises that are good at hardware, optical devices, FPGAs, etc., familiar with fiber optic sensing principles, familiar with DVS/DAS optical paths, and want to implement distributed fiber optic vibration systems independently.

Build steps.

• Buy optical devices such as narrow linewidth lasers, EDFA, AOM, Raman amplifiers, photodetectors, etc.
• Buy high-speed DAQ cards for distributed fiber optic vibration sensing systems
• Device connection, debugging, and solving various problems encountered during debugging
• Acquire data and do signal demodulation processing to implement your own software program.
