Link performance investigation of industry first 100G PAM4 IC chipset with real-time DSP for data center connectivity

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 100Gb/s up to 40km distance of standard single mode fiber.
