← ScienceWhich outcome occurs when stray electromagnetic fields couple with a high-speed data cable?
A)Reduced signal distortion due to impedance matching
B)Increased bit error rate from induced currents✓
C)Improved data throughput from field enhancement
D)Decreased power consumption from reduced resistance
💡 Explanation
When external electromagnetic fields couple with a data cable, electromagnetic induction occurs because the changing magnetic field induces currents within the cable conductors, which interferes with the signal and elevates the bit error rate. Therefore increased bit error rate results, rather than distortion reduction, throughput increase, or power reduction which require specific cable configurations, optimized signals or material changes.
