Which outcome occurs when fiber optic signal strength is significantly reduced after several kilometers?

💡 Explanation

An increased bit error rate results because signal attenuation weakens the optical pulses, diminishing the receiver's ability to correctly distinguish between bits. Therefore, errors increase rather than a higher signal-to-noise, given lower detectable signal levels across that specific constraint.
