4. I would have thought the variations in patterns would be caused by essentially random imperfections in the crystal growth that no amount of " nearly identical micro-climate " could cause to be exactly replicated across all six sectors.
5. PMD results when two modes that normally travel at the same speed due to fiber core geometric and stress symmetry ( for example, two orthogonal polarizations in a waveguide of circular or square cross-section ), travel at different speeds due to random imperfections that break the symmetry.
6. It's difficult to find random imperfection in a sentence. 用random imperfection造句挺難的
