About the NVIDIA Mellanox MMS4X00-NL-QP1
The NVIDIA Mellanox MMS4X00-NL-QP1 is a hot-swappable OSFP twin-port 2 × 400G DR4 short reach optical transceiver for 2 × 400 Gbps InfiniBand links over single-mode fiber, with a 2 × MPO-12/APC interface and reach of up to 30 m SMF. It is a variant of the MMS4X00-NL 30 m twin-port NDR DR4 named in NVIDIA's Quantum-2 firmware release notes, which require firmware 45.110.234 or later for it. 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. Typical uses: NDR / XDR InfiniBand and 400GbE / 800GbE AI back-end fabrics on Quantum-2, Quantum-X800, Spectrum-4 and Spectrum-X.

MMS4X00-NL-QP1: frequently asked questions
What is the NVIDIA Mellanox MMS4X00-NL-QP1?
The MMS4X00-NL-QP1 is an OSFP twin-port 2 × 400G DR4 short reach module from NVIDIA's LinkX range for 2 × 400 Gbps InfiniBand 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 maximum distance of the MMS4X00-NL-QP1?
NVIDIA specifies the MMS4X00-NL-QP1 for up to 30 m on single-mode fiber per port.
Which fiber and connector does the MMS4X00-NL-QP1 need?
The MMS4X00-NL-QP1 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.
Can the MMS4X00-NL-QP1 be used on an Ethernet port?
NVIDIA qualifies the MMS4X00-NL-QP1 for 2 × 400G DR4 short reach. Ethernet use is not listed for this part number; tell us the switch or adapter model and we will suggest the Ethernet-qualified equivalent from the same family.
Which housing is the MMS4X00-NL-QP1: finned, flat-top, IHS or RHS?
NVIDIA lists the MMS4X00-NL-QP1 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-NL-QP1 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.
Anything to check before ordering the MMS4X00-NL-QP1?
Named only in an NVIDIA firmware footnote; no separate SKU published. Ask us before ordering.
Is your MMS4X00-NL-QP1 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-NL-QP1 price in India and how do I order?
The NVIDIA Mellanox MMS4X00-NL-QP1 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, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
