Introduction
The NVIDIA MMS4X00-NM-T is an Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xDR4 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 500-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 128-ports of 400Gb/s in a 64 cages Spectrum-4 switches.
The Spectrum-4 switches require finned-top OSFP shells for extra transceiver cooling. The main application for MMS4X00-NS-T is linking two switches together with up to 500-meters.
The transceiver combinations guarantee optimal operation in NVIDIA end-to-end Ethernet systems and a rigorous production tested to ensure the best out-of-the-box installation experience, performance, and durability.
