Which defect is amplified when optical fibers undergo stress birefringence?

💡 Explanation

Polarization mode dispersion (PMD) occurs when stress-induced birefringence causes light to split into orthogonal polarization modes traveling at different speeds. Because the modes separate further, PMD increases; therefore PMD is amplified, rather than effects occurring due to different wavelengths.
