Abstract :
In this paper, we briefly review high spectral efficiency optical superchannel transmission with Nyquist pulse shaping. Afterwards we present the principle of coherent optical Nyquist single carrier (SC) systems with frequency domain channel estimation and time domain equalization (FDTDE) with nonlinear compensation scheme coordinated. With this technique, Terabit polarization division multiplexed (PDM) 32 quadrature-amplitude modulation (QAM) superchannel with Nyquist pulse shaping is generated and transmitted experimentally.
