MMA4Z00-NV4-FLT: frequently asked questions
What is the NVIDIA Mellanox MMA4Z00-NV4-FLT?
The MMA4Z00-NV4-FLT is an OSFP twin-port 4 × NVLink4 module from NVIDIA's LinkX range for 800 Gbps NVLink 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 MMA4Z00-NV4-FLT?
NVIDIA's current ordering number for the MMA4Z00-NV4-FLT is 980-9I51C-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-NV4-FLT. They are the same module; quote either and we will match it.
What is the maximum distance of the MMA4Z00-NV4-FLT?
NVIDIA specifies the MMA4Z00-NV4-FLT for NVIDIA does not state a reach for this part; multimode OM4 cabling within the NVLink Switch system.
Which fiber and connector does the MMA4Z00-NV4-FLT need?
The MMA4Z00-NV4-FLT uses a 2 × 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.
Which housing is the MMA4Z00-NV4-FLT: finned, flat-top, IHS or RHS?
NVIDIA lists the MMA4Z00-NV4-FLT as OSFP twin-port, flat 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 MMA4Z00-NV4-FLT 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 MMA4Z00-NV4-FLT?
NVLink-only part. NVIDIA notes a link-up issue on firmware xx.48.10xx+ for the -NS-FLT sibling; ask us for the current advisory.
Is your MMA4Z00-NV4-FLT 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-NV4-FLT price in India and how do I order?
The NVIDIA Mellanox MMA4Z00-NV4-FLT 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 980-9I51C-00NS00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
