NVIDIA OSFP Module MMS4X50NM Twin Port 800Gbps 2xFR4 2xNDR 2xLC-LC

SKU CH-WPQ1-6YDVJ

Twin-port OSFP transceiver delivering 800 Gbps through two FR4 lanes and two NDR links with dual LC connectors

  • Twin-port design doubles link density per slot
  • 800 Gbps aggregate throughput for high-bandwidth clusters
  • 2x FR4 optics enable 2 km reach per lane
  • 2x LC duplex connectors simplify fibre patching

Twin-port 800 Gbps OSFP transceiver

The NVIDIA MMS4X50NM is a twin-port OSFP module delivering 800 Gbps aggregate throughput. Each port runs at 50 Gbps lanes using FR4 optics and terminates in an LC duplex connector. It is built for high-density NDR interconnects in data-centre spine and leaf fabrics.

Hot-plug OSFP install with LC fibre

The module slides into a standard OSFP cage and locks with a bail latch, requiring no tools. Clean the LC ferrules before mating to avoid insertion-loss spikes. Verify the switch port is configured for NDR speeds and that the fibre polarity matches the A-B patch plan; mismatched polarity is the most common bring-up issue.

Questions about this item

How do I verify the module is operating at 800 Gbps after installation?

Check the link status LEDs on the switch or NIC; a solid green light on each of the two LC ports indicates the 800 Gbps link is up and error-free.

What cables or accessories are included with the twin-port OSFP module?

The module ships with the transceiver only; you must purchase two compatible LC single-mode fibre patch cords separately to complete the 2xFR4 links.
