Abstract:
We successfully demonstrate 400Gbps/carrier data transmission (504Gbps line-rate assuming 25.5% FEC) over 7878km using 126-GBaud PDM-QPSK signal generated by a digital pre-processed analog multiplexed DAC. Spectral efficiency of 3.21bit/s/Hz is achieved with super-Nyquist 125-GHz WDM spacing and optical pre-filtering.
