Which risk increases for fiber-optic communication systems when employing excessively high pump power in Raman amplification?

💡 Explanation

Increased four-wave mixing noise rises because high pump power enhances nonlinear interactions, leading to the generation of spurious signals through the four-wave mixing mechanism. Therefore, excessive power degrades SNR, rather than improving signal transmission since spurious signal rise.
