← ScienceWhich consequence results when signal attenuation exceeds equalization in a submarine fiber optic cable carrying high data throughput?
A)Elevated bit error rate appears✓
B)Increased stimulated Brillouin scattering
C)Greater chromatic dispersion occurs
D)Reduced four-wave mixing develops
💡 Explanation
Increased signal loss results in attenuation because optical power degrades along the cable length, therefore bit errors elevate rather than phase distortions like Brillouin scattering, which relates to non-linear refractive index changes from stronger pulses.
