Transmission of a 127 Gb/s PM-QPSK signal over a 3350 km SMF-only line with chromatic dispersion compensation using real-time DSP Invited

We experimentally confirmed the effectiveness of chromatic dispersion compensation by overlap frequency-domain equalization in real-time digital signal processing for a 127 Gb/s polarization-multiplexed quadrature phase shift keying (PM-QPSK) signal up to 56,200 ps/nm. We verified a penalty lower th...

Zusammenfassung:	We experimentally confirmed the effectiveness of chromatic dispersion compensation by overlap frequency-domain equalization in real-time digital signal processing for a 127 Gb/s polarization-multiplexed quadrature phase shift keying (PM-QPSK) signal up to 56,200 ps/nm. We verified a penalty lower than 0.55 dB for accumulated dispersion over a 3350 km single-mode-fiber- (SMF-) only transmission line. We also demonstrated the transmission of a 127 Gb/s PM-QPSK signal in a 50-GHz-spacing 5-channel wavelength division multiplexing configuration over the same SMF-only line with a received Q factor of 10.1 dB.
