Recently, Shanghai Kunlian Information Technology Co., Ltd. has made another significant advancement in the field of Distributed Optical Fiber Sensing (DAS). The company's independently developed high-performance DAS demodulation system, the DAS-U250M, has been officially launched to the market. This marks a solid step forward for Kunlian Technology on the path towards self-reliance in core optical fiber sensing technologies.

The DAS-U250M system is specifically designed for precise vibration monitoring and acoustic wave acquisition in extreme environments. It features a high sampling rate of 250 MSPS, 4-channel synchronous ADC acquisition, and is combined with a 2-channel, 14-bit high-precision DAC transmission module. This enables multi-scenario, high-sensitivity, and high-stability signal detection and processing. The system supports a PCIe 3.0 x8 high-speed data transmission interface, is built upon a Xilinx high-performance FPGA platform, and possesses robust real-time data processing capabilities with low-latency response.

This series of DAS systems from Kunlian Technology has been widely applied in various fields, including oil and gas pipeline monitoring, high-speed railway and tunnel safety early warning, seismic exploration, border security, and underwater surveillance. By leveraging core performance features such as "coherent fading suppression, polarization fading noise control, and a spatial resolution better than 5 meters," the system addresses the challenges of stability and accuracy faced by traditional distributed sensing systems in complex environments.

"We have not only conducted deep optimization at the hardware level but also achieved key breakthroughs in FPGA algorithms and system integration," stated the R&D lead at Kunlian Technology. "Moving forward, the company will continue to increase R&D investment, focusing on the development of next-generation DAS demodulation technologies with higher sampling rates, longer transmission distances, and higher resolution, thereby driving the evolution of distributed optical fiber sensing towards greater intelligence, precision, and practicality."

As a significant force in domestic Distributed Optical Fiber Sensing system R&D, Kunlian Technology consistently adheres to the principle of independent innovation, dedicating itself to creating perception system products with international competitiveness. The company also welcomes partners from fields such as energy, power, transportation, and scientific research to jointly explore the in-depth application of DAS technology and create a new future for intelligent sensing together.
