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.

High-speed data acquisition card for DVS system，100MSps DAQ

What was the difference between DAS and DVS before. How easy it is to develop and how it compares in terms of sensitivity.

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.
