← TechnologyWhich impairment results when signal processing inadequately equalizes channel dispersion in fiber optic communication?
A)Reduced Bit Error Rate
B)Lower Signal-to-Noise Ratio
C)Increased Inter-Symbol Interference✓
D)Elevation of Optical Return Loss
💡 Explanation
Inadequate channel equalization causes increased inter-symbol interference because pulse spreading overlaps adjacent symbols, making signal discrimination at the receiver difficult; therefore bit errors increase, rather than reducing interference because the chromatic dispersion isn't flattened in the fibers.
