← ScienceWhich consequence results when the spectral width exceeds photodiode bandwidth?
A)Increased intersymbol interference occurs✓
B)Improved signal-to-noise ratio results
C)Reduced chromatic dispersion appears
D)Enhanced carrier frequency stability happens
💡 Explanation
Increased intersymbol interference occurs because chromatic dispersion broadens pulses where the mechanism involves group velocity dispersion effects; therefore the symbols overlap, rather than distinct separation, in absence of compensation methods.
