MELLANOX MMS4X00-NM-FLT NVIDIA TWIN PORT TRANSCEIVER 800GBPS 2XNDR OSFP 2XMPO12 APC

The NVIDIA MMS4X00-NM is an InfiniBand and Ethernet 800Gb/s, 2x400Gb/s Twin-port OSFP, DR8 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 (DR8) design uses 100G-PAM4 modulation and has a maximum fiber reach of 500-meters using 8 single mode fibers. The 500-meter length assumes two optical patch panels in the link. The Twin-port DR8 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 depending on the protocol of the switch attached to. The Quantum-2 and Spectrum-4 switches require finned-top OSFP shells for extra transceiver cooling. The main application for MMS4X00-NM is linking two switches together from 100-to-500- meter link length. 500-meter transceivers have purple marking. A flat top version (-NM-FLT) is offered for DGX-H100 systems. The 500-meter MMS4X00-NM part is similar to the 100-meter MMS4X00-NS, only extensively tested up to 500-meters use cases and may employ a different error correction scheme. 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.
