Abstract :
Threefold 1.2-Tb/s optical polarization-division-multiplexing (PDM) single-carrier frequency-division-multiplexing (SCFDM) and orthogonal-frequency-division-multiplexing (OFDM) superchannel multicasting, utilizing multiple-pump four-wave mixing (FWM) by highly nonlinear fiber (HNLF), is proposed and experimentally demonstrated in this paper. The optical signal noise ratio (OSNR) penalties of the newly generated SCFDM and OFDM superchannels, at the bit error rate (BER) of 10-3, are 2.6 dB and 3.1 dB, respectively. Optimal pump power and signal power are also investigated for the two superchannels. The two superchannels have similar optimal pump power, whereas the SCFDM superchannel has higher optimal signal power due to the lower peak-to-average power ratio (PAPR).
