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.
The G-1550-200-L-D-T-AA-G3-T-L is 1550nm fiber-coupled acousto-optic modulator(AOM), Frequency 200Mhz, deal for fiber optic sensing system applications.
Introduction of data acquisition card for distributed fiber optic vibration monitoring system, 100M sampling rate, PCIe interface with demodulation algorithm.
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.
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.
