← TechnologyWhich outcome occurs when chromatic dispersion exceeds multiplexing guard interval allocation?
A)Increased inter-symbol interference occurs✓
B)Reduced signal-to-noise ratio occurs
C)Increased bit error rate results
D)Optical carrier suppression results
💡 Explanation
Increased inter-symbol interference (ISI) occurs because chromatic dispersion causes pulse spreading, therefore symbols overlap in time-domain beyond the guard interval managed through time division multiplexing. Rather than bit errors or carrier suppression, adjacent symbols begin to collide.
