Which risk fundamentally limits data rate scaling in single-mode optical fiber?

A)Modal dispersion broadens optical pulses

B)Chromatic dispersion reduces signal fidelity✓

C)Nonlinear scattering attenuates weaker signals

D)Fresnel reflections generate signal echoes

💡 Explanation

Chromatic dispersion limits data rate because different wavelengths of light travel at slightly different speeds, causing pulse broadening and inter-symbol interference; therefore the signal integrity degrades rather than suffering signal loss or modal effects by other means
