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.
