Which consequence results when oversampling the received signal in coherent optical receivers?

💡 Explanation

Increased sampling provides redundant information, aiding **equalizer** performance because it allows averaging out of tap noise, thereby enhancing SNR rather than exacerbating dispersion. Phase noise remains a separate impairment, rather than being mitigated at receiver.
