Introduction
The NVIDIA MMA4Z00-NS is an In niBand 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
(2xSR4) uses 100G-PAM4 modulation and has a maximum ber reach of 50-meters using
8 multimode bers. The 50-meter length assumes two optical patch panels in the link.
The Twin-port 2xSR4 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 rmware
supports both In niBand and Ethernet and is automatically enabled based on the switch
protocol.
The Quantum-2 and Spectrum-4 switches require nned-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).

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.
