← TechnologyWhich system behavior results from inadequate guard band spacing in WDM optical fiber?
A)Adjacent channel interference increases sharply✓
B)Chromatic dispersion effects are amplified
C)Polarization mode dispersion becomes dominant
D)Bit error rate remains unaffected overall
💡 Explanation
When the guard band spacing is insufficient, wavelength division multiplexing (WDM) experiences increased adjacent channel interference. This is because spectral spreading impairs orthogonality rather than isolates channels; therefore, data corruption increases greatly, rather than remaining unaffected.
