About the NVIDIA Mellanox MMA4Z00-NS400
The NVIDIA Mellanox MMA4Z00-NS400 is a hot-swappable OSFP single-port 400G SR4 optical transceiver for 400 Gbps InfiniBand and Ethernet links over multimode fiber, with an MPO-12/APC interface and reach of up to 50 m OM4 / 30 m OM3. It is the single-port 400G OSFP SR4 for NDR adapters: a flat-top OSFP that goes in the ConnectX-7 / BlueField-3 OSFP cage and links to one half of a twin-port 800G switch optic (MMA4Z00-NS) or to another NS400. Typical uses: NDR InfiniBand and 400GbE AI/HPC fabrics on ConnectX-7, BlueField-3, Quantum-2 and Spectrum-4.

MMA4Z00-NS400: frequently asked questions
What is the NVIDIA Mellanox MMA4Z00-NS400?
The MMA4Z00-NS400 is an OSFP single-port 400G SR4 module from NVIDIA's LinkX range for 400 Gbps InfiniBand and Ethernet links. It plugs into an OSFP port on an NVIDIA / Mellanox switch, adapter or DPU and is used for NDR InfiniBand and 400GbE AI/HPC fabrics on ConnectX-7, BlueField-3, Quantum-2 and Spectrum-4.
What is the NVIDIA SKU for the MMA4Z00-NS400?
NVIDIA's current ordering number for the MMA4Z00-NS400 is 980-9I51S-00NS00. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMA4Z00-NS400. They are the same module; quote either and we will match it.
What is the maximum distance of the MMA4Z00-NS400?
NVIDIA specifies the MMA4Z00-NS400 for up to 50 m on OM4 and 30 m on OM3 multimode fiber.
Which fiber and connector does the MMA4Z00-NS400 need?
The MMA4Z00-NS400 uses a MPO-12/APC connector on multimode fiber (OM3/OM4), at 850 nm. 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.
Does the MMA4Z00-NS400 work for both InfiniBand and Ethernet?
Yes. NVIDIA qualifies the MMA4Z00-NS400 for 400G SR4 (NDR InfiniBand / 400GbE), so the same module runs in InfiniBand mode on Quantum / Switch-IB ports and ConnectX VPI adapters, and in Ethernet mode on Spectrum switches and ConnectX Ethernet ports. The port decides the protocol; the optic does not need to change.
Which housing is the MMA4Z00-NS400: finned, flat-top, IHS or RHS?
NVIDIA lists the MMA4Z00-NS400 as OSFP single-port, flat top (riding heat-sink). 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 MMA4Z00-NS400 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.
MMA4Z00-NS400 vs MMA1Z00-NS400: OSFP or QSFP112?
They are the same 400G SR4 optic in two housings. MMA4Z00-NS400 is OSFP (for OSFP-cage ConnectX-7 / BlueField-3 cards). MMA1Z00-NS400 is QSFP112 (for QSFP112-cage cards). Check which cage your adapter has; the optics interoperate over fiber.
Is your MMA4Z00-NS400 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 MMA4Z00-NS400 price in India and how do I order?
The NVIDIA Mellanox MMA4Z00-NS400 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 980-9I51S-00NS00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
