Abstract :
We experimentally demonstrate the successful modulation and error-free detection of three eigenvalue nonlinear frequency division multiplexed (NFDM) signals over 1800 km based on the recently developed nonlinear Fourier transform theoretical framework with digital coherent receivers. The three eigenvalues are located on the upper-half complex plane and are modulated by independent ON-OFF keying signals, thus forming 3-bit NFDM symbols for nonlinear fiber transmissions.
