The method of the present invention includes: obtaining a mechanical model of optical fiber simulation, and assigning cutting conditions; performing crack growth calculation on the model, and geometrically processing the calculation result, and extracting a three-dimensional data set; and obtaining the simulated fracture surface type of the optical fiber by interpolating the data set , and establish a reference evaluation surface for fiber cutting; calculate the error value between the fiber simulation fracture surface type and the fiber cutting reference evaluation surface, and output the cutting conditions corresponding to the fiber simulation fracture surface type whose error value is less than the set threshold. The invention obtains the optimal cutting condition of the optical fiber in a simulated manner, and can cut high-quality fracture surfaces without grinding.
