Long-Term Reliable >200-Gb/s Directly Modulated Lasers with 800GbE-Compliant DSP

We demonstrate the long-term reliable operation of a 70-GHz-class DFB+R laser and its capability of 108-GBd PAM-4 signaling under +4.8-ps/nm dispersion using ultra-low complexity equalizations as well as faster-than-Nyquist PAM-2 signaling up to 280 GBd.
