This is a data acquisition card for distributed fiber optic vibration monitoring system (DVS) with built-in TTL pulse signal trigger output function to provide signal to the AOM driver, saving extra signal generator (AWG) and reducing the integration difficulty and complexity of the system.

[EDFA] 2023-11-04 23:53:50

The module integrates both an EDFA erbium-doped fiber amplifier and a Raman fiber amplifier inside the module, which significantly reduces system complexity, increases reliability, and reduces size compared to conventional EDFA and Raman amplification systems. The front-end EDFA is available as a pulsed EDFA or an amplified EDFA suitable for ultra-long-range fiber optic sensing systems or high-speed fiber optic communication systems.

A tutorial on how to wire a distributed fiber optic vibration sensing system DVS/DAS, and notes related to the wiring process.

The software programming of DVS/DAS system is actually for the interface programming of data acquisition card, you can use C, C++, Python, labview, matlab, etc. for programming.

DVS/DAS system with ultra-narrow linewidth lasers, 1550nm 3k linewidth 20mW lasers are usually used in our system.
