Which risk increases when a submarine telecommunications fiber optic cable experiences localized seawater ingress?

💡 Explanation

Increased chromatic dispersion penalty results because seawater's increased refractive index changes the speed of light at different wavelengths, leading to pulse broadening via chromatic dispersion; a higher penalty results for longer distances, therefore signal integrity is compromised, rather than power transfer being impacted like Raman or Brillouin.
