Which risk strongly increases when polarization-maintaining fiber is kinked?

💡 Explanation

Kinks introduce stress, causing birefringence changes; therefore, the polarization extinction ratio drops severely, because of polarization mode coupling, rather than modal dispersion, which is due to waveguide geometry imperfections or reduced chromatic aberration corrections.
