MMS1W50-HM: frequently asked questions
What is the NVIDIA Mellanox MMS1W50-HM?
The MMS1W50-HM is a QSFP56 InfiniBand HDR FR4 / 200GBASE-FR4 module from NVIDIA's LinkX range for 200 Gbps InfiniBand and Ethernet links. It plugs into a QSFP56 port on an NVIDIA / Mellanox switch, adapter or DPU and is used for HDR InfiniBand and 200GbE fabrics for HPC, AI training and storage on ConnectX-6 / Quantum / Spectrum-3.
What is the NVIDIA SKU for the MMS1W50-HM?
NVIDIA's current ordering number for the MMS1W50-HM is 980-9I055-00H000. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMS1W50-HM. They are the same module; quote either and we will match it.
What is the maximum distance of the MMS1W50-HM?
NVIDIA specifies the MMS1W50-HM for up to 2 km on single-mode fiber.
Which fiber and connector does the MMS1W50-HM need?
The MMS1W50-HM uses a Duplex LC connector on single-mode fiber (OS2), at 1310 nm band (CWDM, 4 lanes). Both ends of the link must use the same optical standard.
Does the MMS1W50-HM work for both InfiniBand and Ethernet?
Yes. NVIDIA qualifies the MMS1W50-HM for InfiniBand HDR FR4 / 200GBASE-FR4 (2 km), 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.
Is the MMS1W50-HM compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with QSFP56 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 MMS1W50-HM 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 MMS1W50-HM price in India and how do I order?
The NVIDIA Mellanox MMS1W50-HM 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 980-9I055-00H000), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
