Measurement of stresses in optical fiber and preform
Abstract:
A method of measuring the stresses, residual or applied, in an optical fiber or preform is presented. It is shown that the stress profiles can be obtained from the Abel transform of the derivative of the retardation. The axial stress profile is shown to bear the same shape as the refractive-index profile. Measurement results indicate that the applied tension during the fiber drawing process is frozen into the fiber, consequently affecting the intrinsic strength of the fiber. The method of estimating the fiber drawing tension from the fiber stress profile is also given.

The process begins by slicing the tube at critical points and analyzing the internal forces and stress components at these sections, focusing on the centroid. Normal stresses, generated by axial forces and bending moments, are either compressive or tensile and vary across the section from...
