Which mechanism limits signal distance through submarine fiber cables?

💡 Explanation

Material absorption attenuates light, because fiber interacts with photons, converting light energy to heat in the fiber material. Therefore, intensity decreases exponentially with distance, rather than signals being corrupted by scattering, requiring repeaters.
