Which limitation arises within wavelength-division multiplexing due to slight refractive index variations across transponders?

💡 Explanation

Nonlinear crosstalk severity escalates because slight refractive index variations cause constructive or destructive interference of channels during Four-Wave Mixing process, therefore signal integrity degrades, rather than chromatic dispersion alone dominating within individual channel bandwidth.
