摘要

By applying recirculating frequency shifter technology to generate optical comb as neighboring channels, we have experimentally investigated the interchannel nonlinear tolerance of 256-Gbit/s polarization-division multiplexing return-to-zero 16-ary quadrature amplitude modulation (PDM-RZ-16QAM) in a co-propagation with 32-Gbaud on-off keying, binary phase-shift keying, quadrature phase-shift keying (QPSK) signals in 792-km large-area fiber transmission system. The results show that the experimental back-to-back optical signal-to-noise ratio requirement of 256-Gbit/s (32-GBaud) PDM-RZ-16QAM signal is shifted by 4.8-dB penalty in comparison with the theoretical limits. The cross-phase modulation (XPM) tolerance for 256-Gbit/s PDM-RZ-16QAM in 32-Gbaud phase-modulated neighboring channels is better than in 32-Gbaud intensity-modulated neighbors. Moreover, the performance of XPM tolerance for 256-Gbit/s PDM-RZ-16QAM in 32-Gbaud QPSK neighboring channels is the best among other kinds of modulation neighboring formats.
