MMA4Z00-NS 800Gb/s Twin-port OSFP, 2x400Gb/s Multi-mode SR8, 50m

Introduction

The NVIDIA MMA4Z00-NS is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, DR8 multi-mode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel multi-mode, short reach 8-channel (SR8) uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using 8 multi-mode 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.

The transceiver combinations guarantee optimal operation in NVIDIA end-to-end systems and customer networking solutions. Rigorous production testing ensures the best out-of-the-box installation experience, performance, and durability.
