Twin-Port 800Gbps OSFP Transceiver

This NVIDIA MMS4X00-NM transceiver delivers 800Gbps aggregate throughput using two NDR ports in a finned-top OSFP form factor. It is built for high-density switch ports that require air-cooled operation and dual 400Gbps fibre links.

Dual MPO-12/APC Single-Mode Interface

The module uses two MPO-12/APC connectors at 1310nm over single-mode fibre, supporting link distances up to 500m. Eight electrical lanes run at 100G-PAM4, mapped to two optical groups of four lanes each for 400Gbps per port.

Suits 800G DR8 Links in Air-Cooled Switches

Network engineers deploying 800G DR8 connections with dual-cable routing will match this part exactly. Buyers who need a single 800G port, a different connector type, longer reach or a flat-top OSFP for liquid-cooled chassis should look at other modules.

Questions about this item

What does the 800 Gbps transfer rate mean when the transceiver is installed in a switch?

It delivers two 400 Gbps lanes over single-mode fiber, each using four 100G-PAM4 optical channels, for an aggregate 800 Gbps link up to 500 m.

How does the OSFP form factor with MPO-12/APC connectors limit the cabling I can use?

The module accepts two MPO-12/APC single-mode patch cords; each connector carries four fiber pairs, so you need straight 400 Gbps cables that match the 1310 nm wavelength.

What clearance does the finned-top OSFP design require in my rack?

The finned heat-sink adds height above the standard OSFP cage; verify your switch chassis allows the extra vertical space for airflow before installing.
