Weak-Reflection Fiber Bragg Grating Micro-Strain Sensing Cable

The weak-reflection fiber Bragg grating (FBG) micro-strain sensing cable is a high-sensitivity fiber-optic sensing product designed specifically for micro-strain monitoring of structures. It is suitable for embedded and surface-bonded installation. The product adopts a tight-buffered weak-reflection FBG structure combined with a fiber-reinforced layer design, providing good lateral compression resistance, mechanical strength, and strain transfer performance. With a compact structure and small outer diameter, the cable can sensitively detect tiny strain changes in structures and is suitable for long-term strain monitoring of civil engineering, infrastructure, and industrial structures.
