← ScienceWithin fiber optic cables, which effect increases because of lower wavelength propagation?
A)Material absorption loss increases✓
B)Modal dispersion effect decreases
C)Refractive index becomes stabilized
D)Numerical aperture value narrows
💡 Explanation
Material absorption loss increases at lower wavelengths due to photons having higher energy, therefore more vibrational excitation occurs. This phenomenon is the increased attenuation, rather than decreased dispersion or stabilization because less energy available avoids material disturbances.
