Performance Impact of Inline Chromatic Dispersion Compensation for 107-Gb/s Coherent Optical OFDM

In this letter, we conduct experimental demonstration and simulation analysis on the dispersion map nonlinearity influence on coherent optical orthogonal frequency-division-multiplexed systems. The system Q performance is compared between inline dispersion compensated systems and noncompensated systems. We identify three contributions to the Q degradation for the inline dispersion-compensated wavelength-division-multiplexing (WDM) systems, specifically for the 107-Gb/s WDM system: there is about 0.8-dB penalty due to the dispersion-compensation fiber (DCF) loss, 0.4 dB from DCF nonlinearity, and 1.6 dB from the dispersion map. We find that at the optimum launch power, the Q -factor degradation from DCF impact, is, respectively, 2.7, 2.2, and 2.8 dB for the data rate of 10.7-, 42.8-, and 107-Gb/s WDM systems.
