Which outcome occurs when signal attenuation increases excessively in fiber optics?

💡 Explanation

Excessive attenuation degrades signal integrity because the diminished signal power becomes comparable to the background noise floor; therefore, the signal-to-noise ratio decreases, rather than signal quality increasing or dispersion effects dominating.
