NVIDIA MMS4X50-NM 800 Gbps OSFP twin port SFP transceiver 2 km

SKU CH-7ZFV-VP2GS MPN MMS4X50-NM

Twin-port OSFP transceiver delivering 800 Gbps over single-mode fibre up to 2 km

  • Compatible BrandNVIDIA
  • Twin-port OSFP delivers 800 Gbps aggregate throughput
  • Two 400 Gbps lanes enable high-density 800 Gigabit Ethernet links
  • Single-mode fibre at 1310 nm supports 2 km reach
  • LC duplex connectors simplify patching in dense racks
  • Finned module design aids thermal management in hot aisles

Twin-port 800G OSFP module

This NVIDIA transceiver delivers 800 Gbps aggregate throughput across two 400 Gbps lanes in a single OSFP form factor. It uses 1310 nm single-mode optics with dual LC connectors to reach distances up to 2 km. The finned housing aids thermal management in dense switch and router line cards.

High-density data-centre links

Suited for operators building 400 Gbps or 800 Gbps interconnects between switches, routers or accelerated compute clusters over duplex single-mode fibre. Not intended for multi-mode environments, shorter-reach copper deployments, or single-port 800G modules where only one lane is needed.

Dual 400G FR4 lanes

The decisive specification is the twin 400G FR4 optical interface providing two independent 400 Gbps channels in one OSFP cage. Buyers needing a different reach, lane count or connector type must select another module.

Questions about this item

How do I install the NVIDIA MMS4X50-NM transceiver and which step is often missed?

Insert the OSFP module into the cage until it clicks, then connect both LC duplex cables to the two ports; the step often missed is seating both LC connectors fully so each 400 Gbps lane locks.

What maintenance or replacement will the NVIDIA MMS4X50-NM need later?

Clean the dual LC ferrules with a lint-free wipe and isopropyl alcohol whenever dust builds up; replace the module only if link errors persist after cleaning.

What limit appears first on the NVIDIA MMS4X50-NM under sustained 800 Gbps load?

The 2 km reach on 1310 nm single-mode fiber is the first bound; signal margin drops before any thermal throttle on the finned OSFP housing.
