Technical guides, application topics and featured articles for distributed sensing and photodetector hardware.
Option 1: Using DAS Integrated Module and DAQ Board. Option 2: Built using separated components such as lasers, acousto-optic modulation, EDFA, and balanced detectors. Option 3: DAS hardware all-in-one solution.
So if you want to modulate a narrower pulse width, the rise time of your AOM must be matched. Otherwise it is theoretically impossible to modulate a narrower pulse width due to the AOM's rise time.

We provide all the hardware needed for cost-effective distributed vibration sensing systems, including integrated modules, as well as components such as lasers, AOMs, and acquisition cards.
In addition to providing DVS/DAS modules, we also provide free after-sales technical support services. We have many years of research and development of the whole machine and a wealth of field experience, which is equivalent to having helped you solve the various difficulties in the process of DVS development and implementation in advance, saving you at least 1.5× time and energy.
