In an ordinary (non-polarization-maintaining) fiber, different polarization modes have the same nominal phase velocity due to the fiber''s circular symmetry. Stress induced birefringence in such a fiber, or bending of the fiber, will cause a tiny amount of crosstalk between different modes. Over the length of the fiber this tiny coupling between modes transfers significant amounts of power between them, completely changing the wave''s net state of polarization. Polarization changes due to stress in a fiber
