← ScienceWhich consequence results downstream when a pulsed laser's pulse duration broadens excessively within an optical fiber?
A)Increased energy propagation efficiency
B)Reduced data transmission bandwidth✓
C)Enhanced signal-to-noise ratio
D)Improved spectral resolution of output
💡 Explanation
Excessive pulse broadening reduces data transmission bandwidth because chromatic dispersion causes different wavelengths to travel at different speeds, therefore pulses overlap, rather than remaining distinct, causing errors and limiting capacity.
