← ScienceWhich condition leads to signal loss in single-mode fiber optic communication?
A)Birefringence-induced polarization mode dispersion✓
B)Increased numerical aperture acceptance angle
C)Raman scattering gain coefficient decline
D)Chromatic dispersion compensation improvement
💡 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.
