Weak-Reflection Fiber Bragg Grating Micro-Strain Sensing Cable

The weakly reflective fiber Bragg grating (FBG) micro strain sensing cable can be divided into weakly reflective FBG array type and weakly reflective chirped grating type according to the grating form. According to the packaging structure, it can be divided into metal tube packaging, polymer tight packaging, and armored optical cable type. According to the application scenario, it can be divided into buried type, surface adhesive type, and cable integrated type.
