Which behavior arises from exceeding waveguide dispersion limits?

A)Increased signal propagation delays
B)Reduced effective mode area
C)Enhanced Raman scattering efficiency
D)Pulse broadening with distance

💡 Explanation

Pulse broadening occurs because chromatic dispersion causes differing frequency light to propagate at different speeds; therefore, the pulse spreads, rather than maintaining its shape, since shorter wavelengths travel slower.
