Which mechanism limits maximum data transfer efficiency in single-mode optical fiber over long distances?

💡 Explanation

When light propagates in single-mode fiber, chromatic dispersion occurs because different wavelengths travel at slightly different speeds, broadening the optical pulses and causing them to overlap, limiting data rate. Therefore chromatic dispersion limits efficiency, rather than refraction, polarization mode attenuation, or plasmon resonance which are less significant in single-mode fiber.
