Product Details
The NVIDIA MMS4X00-NS is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2x2xDR44 single mode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel single mode, datacenter reach 8-channel (2xDR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 100-meters using 8 single mode fibers. The 100-meter length assumes two optical patch panels in the link.
The Twin-port 2xDR4 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 Quantum-2 and Spectrum-4 switches require finned-top OSFP shells for extra transceiver cooling. The main application for MMS4X00-NS is linking two switches together with up to 100/500-meters. 100-meter transceivers have a white stripe, and the 500-meter transceivers have purple stripe.
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 InfiniBand systems and a rigorous production tested to ensure the best out-of-the-box installation experience, performance, and durability.
