← ScienceWhich outcome occurs when a signal frequency approaches the Bragg condition within a fiber-optic cable?
A)Signal attenuation shows increased Rayleigh scattering
B)Stimulated Raman propagation enhances amplification
C)Signal reflection initiates Bragg grating formation✓
D)Four-wave mixing prevents signal overlap
💡 Explanation
When the signal approaches the Bragg condition, constructive interference initiates Bragg grating formation via periodic refractive index changes because the index variation reflects the signal back on itself; therefore, the reflection increases, rather than Raman amplification.
