Which risk increases when wavelength division multiplexing (WDM) systems operate beyond their design channel count?

💡 Explanation

Increased channel count causes closer spacing, therefore leading to stronger non-linear interactions. Specifically, increased four-wave mixing occurs because closely spaced wavelengths generate new interfering wavelengths, rather than maintaining signal integrity, disrupting data transmission.
