Which consequence results when guard bands are insufficient within a DWDM system?

💡 Explanation

With insufficient optical guard bands, the tails of adjacent channel spectra overlap, causing crosstalk because of wavelength division multiplexing; therefore, data corruption occurs rather than decreased dispersion compensation linked to fiber imperfections.
