← ScienceWhich constraint affects data stream capacity on optical fibers?
A)Chromatic dispersion causes pulse broadening✓
B)Fresnel losses affect signal absorption
C)Raman scattering amplifies signal pathways
D)Mode partitioning improves noise reduction
💡 Explanation
Chromatic dispersion limits optical fiber capacity because different wavelengths propagate at different speeds, leading to pulse broadening and inter-symbol interference along the optical waveguide. Therefore, capacity suffers, rather than signal improvements, from scattering or lessened absorptions.
