Which consequence results when accumulated chromatic dispersion affects optical signal transmission?

A)Increased inter-symbol interference
B)Reduced laser power consumption
C)Enhanced signal-to-noise ratio
D)Decreased fiber refractive index

💡 Explanation

In fiber optic cables, chromatic dispersion leads to pulse broadening. Because longer wavelengths travel faster than shorter ones across the fiber, increased inter-symbol interference results, therefore limiting transmission speeds, rather than SNR enhancements or refractive index shifting.
