← TechnologyWhich data loss increases during fiber optic wavelength division multiplexing with imperfect channel isolation?
A)Inter-symbol interference (ISI)
B)Four-wave mixing (FWM)✓
C)Chromatic dispersion penalty
D)Polarization mode dispersion (PMD)
💡 Explanation
Imperfect channel isolation during wavelength division multiplexing causes cross-talk, leading to four-wave mixing (FWM). FWM generates new frequencies from existing wavelengths causing signal distortion therefore increasing data loss, rather than the time-based distortions of ISI.
