NVIDIA MMA4Z00-NS is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, DR8 multimode, parallel, 8-channel transceiver using two,
4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel multimode, short reach 8-channel (SR8) uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using 8 multimode fibers.
The 50-meter length assumes two optical patch panels in the link.
The Twin-port SR8 transceiver is a key NVIDIA innovation with two internal transceiver engines enabling 64-ports of 400Gb/s in a 32-OSFP cage Quantum-2 switch. Spectrum-4 switches have 32 or 64 cages and enable 64-128 400G ports.
The transceiver firmware supports both InfiniBand and Ethernet and is automatically enabled based on the switch protocol.
The Quantum-2 and Spectrum-4 switches require finned-top OSFP shells for extra transceiver cooling. The main application for MMA4Z00-NS is linking two switches together with up to 50-meter transceivers (marked blue).
A flat-top version offered for liquid-cooled and DGX H100 Cedar7 systems links.

In addition to NVIDIA MMA4Z00-NS QSFP-800G-SR8 , Liyuan Tech supply a wide range of other NVIDIA optical transceivers. If you have any need or interest, please feel free to send inquiry to global@chn-liyuan.com
