Product Overview

To assist researchers, system developers, and product engineers in the field of fiber optic sensing in building their own distributed fiber acoustic monitoring systems more conveniently, Shanghai Kunlian Technology has introduced the DAS Integrated Module. This module highly integrates multiple optoelectronic components from traditional DAS systems—such as light sources, modulation, amplification, and control—into a compact structure comparable to the size of a "slightly thick book," significantly simplifying the system construction process.

Users only need to equip an industrial computer (or standard PC) with a high-speed data acquisition card to complete all the hardware preparation for a DAS system. The remaining development efforts can then be focused on implementing the host computer software, signal processing algorithms, and system application logic. Shanghai Kunlian Technology also provides complimentary technical support services to help you quickly complete the verification and integration of your DAS system.

Target Users

Fiber Optic Sensing System Manufacturers: Already have a DAS or DVS product line but wish to reduce hardware costs while ensuring performance, aiming for system redesign or optimization.

System Integrators and Solution Providers: Possess industry demand knowledge and implementation resources, with software development capabilities, and aim to transition from purchasing others' products to launching their own branded DAS systems.

Universities and Research Institutions: Have expertise in algorithms and signal processing, are in the process of building distributed fiber optic sensing experimental platforms, and wish to achieve a complete system with a limited budget.

Other Developers and Innovation Teams: Need to quickly verify concepts or prototype systems, seeking a plug-and-play DAS core module as a starting point for R&D.
