Distributed optical fiber DAS integrated module

Description
To facilitate the rapid development of fiber optic acoustic monitoring systems by researchers and developers in the field of fiber optic sensing, we have integrated the complex optical components of the DAS system into a single module, which is only slightly thicker than a book. Then, the developers only need to pair it with a high-speed data acquisition card and install it on an industrial control computer (PC), thus completing all the hardware preparations for the DAS system; the rest is to focus on the upper computer and algorithm implementation of the distributed fiber optic acoustic monitoring system.

Characteristics
● High integration (UNL, AOM, EDFA, Raman)
● Modular design allows selection of modules based on sensing distance
● Flexible control methods
● High stability and reliability
● Customizable external structure design
