Fiber Bragg Grating Strain Cable

The Fiber Bragg Grating Strain Cable is a distributed multi-point strain monitoring product based on Fiber Bragg Grating (FBG) sensing technology. Multiple FBG sensing units are embedded at specified intervals into a fiberglass-reinforced optical cable with a diameter of approximately 1 mm, enabling continuous multi-point measurement of structural strain. The product features high measurement accuracy, a compact structure, flexible measuring-point spacing, and no need for intermediate splicing. Up to 18 strain measuring points can be arranged per string. It is suitable for strain monitoring and safety assessment in bridges, tunnels, pile foundations, dams, building structures, and other engineering projects.
