Abstract :
A modulation-format independent optical channel defragmentation with high frequency-granularity and spectral efficiency is demonstrated by using a wavelength-selective-switch and IQ modulator-based frequency shifters. The system achieves bit-error-rate under 10-9 with 12.5 and 25 GHz frequency shifts.
