Which mechanism limits signal propagation speed in a long submarine communication cable?

💡 Explanation

When signals travel long distances in submarine cables, chromatic dispersion broadens the pulses, causing Inter-symbol interference (ISI) because different wavelengths propagate at slightly different speeds and overlap, limiting reliable speed. Therefore, ISI results, rather than attenuation, noise, or reflections which are mitigated by repeaters, low temperature, careful termination respectively.
