About the NVIDIA Mellanox MMS4C10-XM800
The NVIDIA Mellanox MMS4C10-XM800 is a hot-swappable OSFP single-port 800G DR4 Gen2 optical transceiver for 800 Gbps InfiniBand and Ethernet links over single-mode fiber, with an MPO-12/APC interface and reach of up to 500 m SMF. It is the Gen2 single-port 800G DR4 for XDR InfiniBand and 800GbE adapter ports, the adapter-side partner of the MMS4C10 / MMS4C11 twin-port 1.6T switch optics. XDR 800G optics run four 200G PAM4 lanes per port, for Quantum-X800 InfiniBand and Spectrum-X800 Ethernet fabrics with ConnectX-8 / BlueField-4 adapters. Typical uses: NDR / XDR InfiniBand and 400GbE / 800GbE AI back-end fabrics on Quantum-2, Quantum-X800, Spectrum-4 and Spectrum-X.

MMS4C10-XM800: frequently asked questions
What is the NVIDIA Mellanox MMS4C10-XM800?
The MMS4C10-XM800 is an OSFP single-port 800G DR4 Gen2 module from NVIDIA's LinkX range for 800 Gbps InfiniBand and 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 MMS4C10-XM800?
NVIDIA's current ordering number for the MMS4C10-XM800 is 980-9IAY0-00XM00. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMS4C10-XM800. They are the same module; quote either and we will match it.
What is the maximum distance of the MMS4C10-XM800?
NVIDIA specifies the MMS4C10-XM800 for up to 500 m on single-mode fiber.
Which fiber and connector does the MMS4C10-XM800 need?
The MMS4C10-XM800 uses a MPO-12/APC (single-mode) connector on single-mode fiber (OS2), at 1310 nm (4 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.
Does the MMS4C10-XM800 work for both InfiniBand and Ethernet?
Yes. NVIDIA qualifies the MMS4C10-XM800 for 800G DR4 Gen2 (XDR InfiniBand + 800GbE), 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 MMS4C10-XM800: finned, flat-top, IHS or RHS?
NVIDIA lists the MMS4C10-XM800 as OSFP single-port, RHS. 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 MMS4C10-XM800 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.
Is your MMS4C10-XM800 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 MMS4C10-XM800 price in India and how do I order?
The NVIDIA Mellanox MMS4C10-XM800 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 980-9IAY0-00XM00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
