To study and fabricate the fiber terminal-faces in both theory and experiment，the fracture principle of a brittle uniform solid material is analyzed and discussed concretely according to the solid fracture mechanics. It is concluded that the fracture route in a point of the columniform uniform solid material has the characteristics of stability and uniqueness in spreading trends. A simple fabricating method to cut the optical fiber terminal-faces is proposed, and an experiment device based on the method is developed. During the cutting experiments, the optical fiber terminal-faces are fabricated with different diameters of 0.2 mm, 0.3 mm, 0.6 mm, 0.8 mm and 1 mm. Then,a reading-microscope and visible laser transmission methods are adopted to measure the optical quality of the obtained fiber terminal-faces. The testing results show that the fiber terminal-faces fabricated by this method can well satisfy the practical application requirements and the probability of high quality for these fiber terminal-faces has reached 100%.
