MMA4Z00-NV4: frequently asked questions
What is the NVIDIA Mellanox MMA4Z00-NV4?
The MMA4Z00-NV4 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 maximum distance of the MMA4Z00-NV4?
NVIDIA specifies the MMA4Z00-NV4 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 need?
The MMA4Z00-NV4 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: finned, flat-top, IHS or RHS?
NVIDIA lists the MMA4Z00-NV4 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 MMA4Z00-NV4 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?
NVLink-only part; ask us before ordering for any other use.
Is your MMA4Z00-NV4 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 price in India and how do I order?
The NVIDIA Mellanox MMA4Z00-NV4 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.
