DAS-M1000 Basic Demodulation Card

The DAS-M1000 is a high-performance Distributed Acoustic Sensing (DAS) demodulation card launched by Shanghai Kunlian Technology. It integrates advanced Coherent Phase-Sensitive Optical Time Domain Reflectometry (ϕ-OTDR) technology, utilizes Xilinx's high-performance FPGA (XCKU115) as the core processing platform, and combines a multi-channel high-speed AD/DA hardware architecture to achieve real-time acquisition, processing, and analysis of vibration signals. Using standard communication optical fiber as the sensing medium without the need for dedicated sensors, the DAS-M1000 enables precise localization and identification of vibration signals at any point over tens of kilometers. It is widely applied in perimeter security, pipeline monitoring, power communication, and other fields.
