← TechnologyWhich consequence occurs when optical fiber dispersion exceeds system limits?
A)Increased bit error rate✓
B)Raised laser power consumption
C)Decreased amplifier saturation
D)Reduced photodiode responsivity
💡 Explanation
Exceeding fiber dispersion limits causes pulse broadening, leading to inter-symbol interference; this outcome arises because **chromatic dispersion** alters signal timing. Therefore, the bit error rate increases, rather than other signal attenuations or detection issues.
