    In this study, the influential factors that impact the strain transfer rate of the optical fiber sensor are analyzed. The fiber sensors' ability to monitor strain distribution in structural materials depends on the bonding characteristic between the material and fiber. The strain transfer tip effect of the distributed fiber sensor is studied; the two parameters, paste length and colloidal shear modulus, are examined to assess the impact on the strain transfer rate. The results show that the strain transfer length can be increased by prolonging the length of the pasted fiber or increasing the shear modulus of the colloid. Adhesive with high shear modulus should be selected in the engineering application, and the paste length (greater than 5 cm) should be pasted at both ends of the paste measuring section to ensure that the strain results are accurate in the measuring section.
