← TechnologyWhich processing delay increases notably when compensating chromatic dispersion?
A)Increased group delay variation✓
B)Reduced polarization mode dispersion
C)Enhanced signal-to-noise ratio
D)Decreased bit error rate
💡 Explanation
Increased delay occurs because chromatic dispersion compensation utilizes a Filter-Induced Phase Shift (FIPS) mechanism, which can induce variations in the group delay of different frequency components. Therefore, group delay variation increases, rather than enhancing SNR because of the complex filter profiles.
