← TechnologyWhich outcome occurs when ambient light bleeds onto an optical fiber within a Dense Wavelength Division Multiplexing (DWDM) system?
A)Increased bit error rate (BER)✓
B)Reduced laser diode lifespan
C)Higher signal-to-noise ratio (SNR)
D)Decreased fiber refractive index
💡 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.
