← ScienceWhich consequence results when significant chromatic dispersion affects optical transmission?
A)Signal pulse broadens impairing bitrate✓
B)Waveguide sustains thermal catastrophic damage
C)Mode scramblers minimize modal differences
D)Reduced laser injection locking bandwidth
💡 Explanation
Increased chromatic dispersion induces pulse broadening, thereby raising the bit error rate because spectral components propagate at different speeds. Therefore, signal integrity diminishes, distorting data rather than the unlikely destruction of the cable or other unrelated mechanisms.
