Which limitation is imposed during long-distance pulse transmission through optical fiber?

💡 Explanation

Modal dispersion restricts total coherence in fiber optics because path length differences affect wave interference, therefore bit error rate increases, rather than bandwidth limitations due to chromatic dispersion under sufficient coherence.
