Which processing effect causes increased bit errors when multi-mode optical fiber core size limitations induce modal dispersion?

💡 Explanation

Increased bit errors occur because the effect of *modal dispersion* causes group delay to broaden optical pulses, therefore adjacent pulses overlap in time, rather than remaining distinct; chromatic dispersion shifts wavelengths instead.
