Data Acquisition Card for Distributed Acoustic Fiber Sensing (DAS) with Pulse Output sends TTL pulses directly to the AOM driver, eliminating the need for an additional pulse generator and greatly reducing system complexity.
GY-DAQA-2510 is a high-performance DAS dedicated data acquisition card, with dual-channel 1GSps synchronous trigger sampling, and comes with AWG function, which can generate 2-channel swept signal output for chirp pulse modulation.
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.
Coherent Detection Module for Distributed Fiber Optic Vibration/Sound Detection (DVS/DAS) and Wind Radar.It is characterized by high signal-to-noise ratio, high reliability and easy integration.
The PZT was used to test the Distributed Fiber Optic Acoustic Sensing System DAS at a location of 50KM, using a repetition frequency of 2000Hz, capable of testing signals at 980Hz.
Introduction of data acquisition card for distributed fiber optic vibration monitoring system, 100M sampling rate, PCIe interface with demodulation algorithm.
distributed fiber optic sensing systems have been widely used in various fields. Distributed fiber optic sensing system uses optical fiber as a sensing element, thus realizing distributed measurement of physical quantities.
How long can a distributed fiber optic vibration sensing system monitor? In the laboratory it can support 80km, in the application site to consider the light decay and other reasons, the maximum available 60km.
The spatial resolution is related to your optical pulse parameter setting, which is set according to the monitoring length of the fiber optic cable. 40km distance we can achieve 5m spatial resolution.
The type of fiber used for distributed fiber optic vibration sensing is single-mode G652, which is a very common fiber, all in our communication fiber optic cable, and is not expensive.
