Impact and Suppression Applications of Coherent Fading in Distributed Acoustic Sensing (DAS) Systems
In Distributed Acoustic Sensing (DAS) systems, distributed perception of vibration or acoustic information along the optical fiber is achieved by injecting narrow-linewidth coherent laser pulses into the fiber, receiving backscattered signals from a multitude of Rayleigh scattering points within the fiber, and demodulating their phase or intensity variations.

Integrated DAS Optical Module
To facilitate researchers, system developers, and product engineers in the optical fiber sensing field in constructing their own Distributed Acoustic Sensing (DAS) systems more efficiently, Shanghai Kunlian Technology has launched an integrated DAS module. This module highly integrates multiple optoelectronic components from traditional DAS systems—such as complex light sources, modulation devices, amplifiers, and control units—into a compact structure roughly the size of a "slightly thick book," significantly simplifying the system setup process. Users only need to pair it with a high-speed data acquisition card installed in an industrial computer (or standard PC) to complete all hardware preparations for the DAS system. The remaining development efforts can then focus on implementing the host computer software, signal processing algorithms, and system application logic. Shanghai Kunlian Technology also offers complimentary technical support services to assist in the rapid validation and integration of the DAS system.
