← ScienceWhich performance drop occurs when coherence degrades within optical fiber?
A)Increased bit error rate✓
B)Reduced laser power output
C)Elevated fiber core temperature
D)Lower refractive index uniformity
💡 Explanation
Increased bit error rate results because modal dispersion alters the phase relationships; this dephasing directly weakens constructive interference otherwise sustaining pulse shape during transmission. This degradation increases errors, therefore impacting communications, rather than directly affecting output power or fiber properties.
