← ScienceWhich risk increases in fiber optic communication when modal bandwidth limits laser pulse width?
A)Chromatic dispersion induced pulse broadening✓
B)Increased stimulated Brillouin scattering intensity
C)Reduced Raman amplification signal efficiency
D)Polarization mode induced data loss
💡 Explanation
Chromatic dispersion causes shorter pulses to spread more because different wavelengths travel at slightly different speeds. Consequently, pulse broadening results, therefore, limiting data transmission, rather than the alternate effects of Brillouin scattering, Raman gain, or polarization management.
