Which mechanism limits data transmission speed in undersea fiber optic cables over long distances?

💡 Explanation

When light pulses travel in optical fibers, different wavelengths experience slightly different propagation speeds due to chromatic dispersion, causing pulse broadening that eventually merges pulses limiting data rate. Therefore chromatic dispersion limits data speed, rather than interference, stress, or thermal expansion effects which are individually managed through shielding and stabilization.
