Abstract
In this paper, we present a performance review of the state of the art PAM4 IC chipset implementation on the mitigation of optical and bandwidth impairments at 100Gbps and beyond. We experimentally demonstrate, for the first time, by employing newly developed PAM4 chipset and direct detection with commercial 25Gbaud devices, the link operates error free under KR4 FEC threshold at 1310nm wavelength(s) for up to 40km distance of standard single mode fiber. It is foreseeable that PAM4 signaling will soon become the viable and cost effective solution for intra and inter data center connectivity for 40/50GbE, 100/400GbE and beyond.
