Which consequence results when spatial coherence decreases through fiber-optic cable?

💡 Explanation

Increased modal dispersion occurs because reduced spatial coherence distributes optical power among more fiber modes, therefore different modes propagate at different speeds, rather than maintaining a single, coherent wavefront.
