Notes (for table above):
Used as 4x split ends with 400G DR4. MPO-12/APC-to-4xLC splitter fibers are not supplied by NVIDIA.
MFP7E30 fibers can be used with QSFP-DD DR4 supporting splits to four 4x100G DR1.
Part List Using 50G-PAM4 Modulation for 200Gb/s InfiniBand and/or Ethernet QSFP56
This section profiles 4-channel, 200Gb/s, QSFP56-based cables and transceivers using 50G-PAM4 modulation for Ethernet and/or InfiniBand from 0.5m-to-2km for use in 200GbE and HDR switches, ConnectX-6 adapters, and BlueField-2/3 DPUs -- all use QSFP56 connectors for DACs, AOCs, and transceivers.
Some parts support both InfiniBand and Ethernet protocols, and some are protocol specific.
InfiniBand HDR cables and transceivers can be used in NVIDIA-only Ethernet systems, but not the reverse.
