Which phenomenon impairs communication due to birefringence in underwater optical cables?

💡 Explanation

Polarization mode dispersion scrambles signal data because varying refractive indices cause different polarization modes to propagate at distinct speeds, therefore degrading signal integrity rather than pure attenuation or reflection effects.
