Introduction
The NVIDIA MMS4X90-NR is an 800Gb/s 2x400Gb/s Twin-port OSFP, 2xLR4 single mode, 8-channel electrical transceiver. This transceiver uses two, 2-fiber, LC Duplex optical connectors each carrying 4-channels of 100G-PAM4. The 8-channel 2xLR4 design uses 100G-PAM4 electrical and optical modulation based on the CWDM4 serial, multiplexed 1310nm wavelength grid.
It has a maximum fiber reach of 2,000-meters which assumes two optical patch panels in the link. The transceiver firmware supports Ethernet.
The Twin-port 2xLR4 transceiver has two internal transceiver engines enabling 128-ports of 400Gb/s Spectrum-4 switches have 64 cages .
The main application for MMS4X90-NR is linking two switches together up to 10,000-meter.
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.
