Dual Polarization Nonlinear Frequency Division Multiplexing Transmission
We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing (NFDM) using the continuous spectrum in 1680 km of normal dispersion fiber, at the net data rate of 25.6 Gb/s. NFDM exhibits a gain of 0.4 dB in $Q$ -factor and 1 dB in total launch power when compared with burst mode OFDM. DGD penalties are shown to be negligible in NFDM transmission.
