Which risk increases as optical fiber's signal bandwidth nears the Nyquist limit during high-speed signal processing?

💡 Explanation

Increased chromatic dispersion sensitivity occurs because high-speed signal processing requires broader bandwidth, therefore increasing susceptibility to pulse broadening. This effect is worsened rather than mitigated when approaching the Nyquist limit; stimulated scattering becomes less relevant.
