Distributed Acoustic Sensing (DAS) System | Up to 60 km


Overview:
The DVS/DAS hardware integrated unit is the hardware component of the distributed optical fiber vibration sensing system (it only comes with the test DEMO software; the application software needs to be developed by the user based on the usage scenario); the integrated unit uses a 3U chassis; the internal of the chassis integrates the DVS/DAS integrated module, the optical modulator driver, the power module, and the industrial control computer; the system industrial control computer is pre-installed with the Windows system. There are FC/APC sensing optical cable interfaces on the back of the chassis, which are used for connecting external sensing optical cables.

Applicable Users:
● Customers who mainly focus on software implementation and algorithms;
● Those who do not want to install the power supply, industrial control computer, and design the chassis by themselves;
● Those who need to go out for experiments and do not want to carry a bunch of spare parts, but want to directly bring a chassis for convenience and simplicity.
