PAM4 vs. NRZ: Why PAM4 is the Core of 400G & 800G Ethernet
PAM4 technology is implemented in 100G Ethernet under the IEEE 802.3cd standard, serving as an upgrade to traditional NRZ modulation.
Key Technologies
The dual protocol capability is available with the 100G-PAM4 series, but fragments for the older 50G-PAM4 and 25G-NRZ devices as some devices are InfiniBand- or Ethernet-specific.
