Which mechanism diminishes signal fidelity in fiber optics?

💡 Explanation

Modal dispersion occurs due to varying path lengths causing constructive and destructive interference. Consequently, signal resolution blurs, because different modes arrive at different times, therefore diminishing signal fidelity in fiber optics, rather than frequency-dependent material absorption.
