In dense wavelength-division multiplexing, which impairment arises with increased channel count?

A)Four-wave mixing amplification occurs
B)Polarization mode dispersion decreases
C)Chromatic dispersion becomes negligible
D)Self-phase modulation bandwidth diminishes

💡 Explanation

Four-wave mixing arises from the Kerr effect, whereby increased optical power from dense channels induces nonlinear interactions; because power levels increase, new frequencies are generated within fiber rather than signal strengthening. Therefore significant inter-channel interference results, rather than mitigating dispersion or improving bandwidth.
