The DAS all-in-one system (pre-packaged systems) uses a 3U chassis. Inside the chassis, all hardware is fully integrated, including a DVS/DAS integrated module, an acousto-optic modulator driver, a power supply module, and an industrial computer. It is ready to use as soon as the optical cable is plugged in, so users only need to focus on developing software algorithms for their own application scenarios. Of course, we also provide demo software with basic functions, capable of vibration monitoring along the entire optical cable, sound playback at a specified location, waterfall plots, and more.
