Which mechanism limits signal transmission distance in uncompensated single-mode fiber optic cables?

💡 Explanation

With increasing distance, chromatic dispersion causes different wavelengths of light to travel at slightly different speeds because of material and waveguide properties, leading to pulse broadening and signal overlap which limits transmission distance. Therefore chromatic dispersion is responsible, rather than conductor resistance, refraction losses or electromagnetic interference which operate via distinct physical mechanism and require different cable types/environments.
