Which condition leads to signal loss in single-mode fiber optic communication?

💡 Explanation

Polarization mode dispersion causes signal degradation because differential group delay broadens pulses, therefore, this condition leads to signal loss, rather than improved signal quality from lower numerical aperture or improved dispersion compensation.
