About the NVIDIA Mellanox MMS4B10-XM
The NVIDIA Mellanox MMS4B10-XM is a hot-swappable OSFP twin-port 2 × 800G DR4 TRO optical transceiver for 2 × 800 Gbps Ethernet links over single-mode fiber, with a 2 × MPO-12/APC interface and reach of up to 500 m SMF. It is the TRO (transmit-retimed optics) 1.6T twin-port DR4 for air-cooled Spectrum-6 Ethernet switches: a lower-power design that retimes only the transmit path. Twin-port 1.6T OSFP optics carry two independent 800G XDR links in one cage; each MPO-12/APC (or LC) port links to a single-port 800G optic at the adapter end or to another twin-port optic switch-to-switch. Breakout: 2 × 800G (one XDR / 800GbE link per port). Typical uses: XDR InfiniBand and 800GbE AI factories on Quantum-X800, Spectrum-X800 / Spectrum-6, GB300 and Vera Rubin systems.

MMS4B10-XM: frequently asked questions
What is the NVIDIA Mellanox MMS4B10-XM?
The MMS4B10-XM is an OSFP twin-port 2 × 800G DR4 TRO module from NVIDIA's LinkX range for 2 × 800 Gbps Ethernet links. It plugs into an OSFP port on an NVIDIA / Mellanox switch, adapter or DPU and is used for XDR InfiniBand and 800GbE AI factories on Quantum-X800, Spectrum-X800 / Spectrum-6, GB300 and Vera Rubin systems.
What is the NVIDIA SKU for the MMS4B10-XM?
NVIDIA's current ordering number for the MMS4B10-XM is 980-9IAJ0-00XM01. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMS4B10-XM. They are the same module; quote either and we will match it.
What is the maximum distance of the MMS4B10-XM?
NVIDIA specifies the MMS4B10-XM for up to 500 m on single-mode fiber per port.
Which fiber and connector does the MMS4B10-XM need?
The MMS4B10-XM 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.
Is the MMS4B10-XM an Ethernet-only part?
Yes. NVIDIA lists the MMS4B10-XM for Ethernet (2 × 800G DR4 TRO) use. For InfiniBand use the NDR / XDR qualified version of the same family.
Which housing is the MMS4B10-XM: finned, flat-top, IHS or RHS?
NVIDIA lists the MMS4B10-XM as OSFP twin-port, IHS. 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 MMS4B10-XM 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.
IHS vs RHS: which 1.6T housing do I need?
IHS (integrated heat-sink) is the finned-top housing for air-cooled switch cages such as Quantum-X800 and Spectrum-X800 front panels. RHS (riding heat-sink) is the flat-top housing for cages that carry their own heat-sink: liquid-cooled switches, GB300 / Vera Rubin NVL72 trays and ConnectX-8 adapters. The optics are identical; only the housing differs, and the wrong one will not seat correctly. Tell us the system and we will supply the right SKU.
Does the MMS4B10-XM support breakout?
NVIDIA lists 2 × 800G (one XDR / 800GbE link per port). Use the matching optics at the far end and a suitable splitter or breakout cable, and enable port splitting on the switch.
Anything to check before ordering the MMS4B10-XM?
IHS version; the RHS version is MMS4B10-XM-RHS.
Is your MMS4B10-XM 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 MMS4B10-XM price in India and how do I order?
The NVIDIA Mellanox MMS4B10-XM 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 980-9IAJ0-00XM01), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
