Which outcome occurs when ambient light bleeds onto an optical fiber within a Dense Wavelength Division Multiplexing (DWDM) system?

💡 Explanation

The signal degrades leading to a higher BER because ambient light increases noise within the optical fiber by stimulating spontaneous emission via Amplified Spontaneous Emission (ASE); therefore, integrity is reduced, rather than maintained, due to non-signal photons influencing the data stream.
