About the NVIDIA Mellanox MMS4X00-NM-T
The NVIDIA Mellanox MMS4X00-NM-T is a hot-swappable OSFP twin-port 2 × 400GBASE-DR4 optical transceiver for 2 × 400 Gbps Ethernet links over single-mode fiber, with a 2 × MPO-12/APC interface and reach of up to 500 m SMF. It is the Ethernet-only ordering version of MMS4X00-NM for Spectrum-4 SN5600 and Spectrum-X 400GbE/800GbE fabrics. Twin-port OSFP optics carry two independent 400G links in one OSFP cage: each MPO-12/APC port links to a single-port 400G optic (MMS4X00-NS400 / MMA4Z00-NS400 class) at the adapter end, or to another twin-port optic switch-to-switch. Breakout: 2 × 400GbE DR4. Typical uses: NDR / XDR InfiniBand and 400GbE / 800GbE AI back-end fabrics on Quantum-2, Quantum-X800, Spectrum-4 and Spectrum-X.

MMS4X00-NM-T: frequently asked questions
What is the NVIDIA Mellanox MMS4X00-NM-T?
The MMS4X00-NM-T is an OSFP twin-port 2 × 400GBASE-DR4 module from NVIDIA's LinkX range for 2 × 400 Gbps Ethernet links. It plugs into an OSFP port on an NVIDIA / Mellanox switch, adapter or DPU and is used for NDR / XDR InfiniBand and 400GbE / 800GbE AI back-end fabrics on Quantum-2, Quantum-X800, Spectrum-4 and Spectrum-X.
What is the NVIDIA SKU for the MMS4X00-NM-T?
NVIDIA's current ordering number for the MMS4X00-NM-T is 980-9I30G-F4NM00. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMS4X00-NM-T. They are the same module; quote either and we will match it.
What is the maximum distance of the MMS4X00-NM-T?
NVIDIA specifies the MMS4X00-NM-T for up to 500 m on single-mode fiber per port.
Which fiber and connector does the MMS4X00-NM-T need?
The MMS4X00-NM-T uses a 2 × MPO-12/APC (single-mode) connector on single-mode fiber (OS2), at 1310 nm (8 parallel lanes). APC connectors have an angled (green) end-face, so use APC patch cords and MPO trunks; a UPC cord will not mate correctly. Both ends of the link must use the same optical standard.
Is the MMS4X00-NM-T an Ethernet-only part?
Yes. NVIDIA lists the MMS4X00-NM-T for Ethernet (2 × 400GBASE-DR4) use, which is what the -T suffix (SKU ...-F4...) marks. For an InfiniBand-capable version ask us for the matching part without the -T suffix.
Which housing is the MMS4X00-NM-T: finned, flat-top, IHS or RHS?
NVIDIA lists the MMS4X00-NM-T as OSFP twin-port, finned top. Finned / IHS housings go in air-cooled switch cages with open OSFP slots; flat-top / RHS housings go in cages that carry their own heat-sink (ConnectX adapters, DGX / GB-series trays, liquid-cooled switches). Fit the housing to the cage, otherwise the module will not seat or cool properly.
Is the MMS4X00-NM-T compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with OSFP ports that list this part in their firmware 'validated and supported cables and modules' table. Send us your switch / adapter model and firmware version and we check it against NVIDIA's support list before dispatch, so you only receive a module that links up in your port.
Does the MMS4X00-NM-T support breakout?
NVIDIA lists 2 × 400GbE DR4. Use the matching optics at the far end and a suitable splitter or breakout cable, and enable port splitting on the switch.
Anything to check before ordering the MMS4X00-NM-T?
Ethernet-only (-T) variant; NVIDIA SKU ...-F4NM00.
Is your MMS4X00-NM-T genuine NVIDIA / Mellanox?
Yes. Next Gen Networks supplies original NVIDIA (Mellanox) LinkX parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them with mlxlink / mlxcables or the switch's transceiver inventory.
What is the MMS4X00-NM-T price in India and how do I order?
The NVIDIA Mellanox MMS4X00-NM-T price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number (or NVIDIA SKU 980-9I30G-F4NM00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
