MMS1V50-WM: frequently asked questions
What is the NVIDIA Mellanox MMS1V50-WM?
The MMS1V50-WM is a QSFP-DD 400GBASE-FR4 module from NVIDIA's LinkX range for 400 Gbps Ethernet links. It plugs into a QSFP-DD port on an NVIDIA / Mellanox switch, adapter or DPU and is used for NDR InfiniBand and 400GbE AI/HPC fabrics on ConnectX-7, BlueField-3, Quantum-2 and Spectrum-4.
What is the NVIDIA SKU for the MMS1V50-WM?
NVIDIA's current ordering number for the MMS1V50-WM is 980-9I160-00W000. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMS1V50-WM. They are the same module; quote either and we will match it.
What is the maximum distance of the MMS1V50-WM?
NVIDIA specifies the MMS1V50-WM for FR4 class: up to 2 km on single-mode fiber (reach not stated on the NVIDIA page).
Which fiber and connector does the MMS1V50-WM need?
The MMS1V50-WM uses a Duplex LC (FR4 standard; NVIDIA page title says MPO) connector on single-mode fiber (OS2), at 1310 nm band (CWDM, 4 lanes). Both ends of the link must use the same optical standard.
Is the MMS1V50-WM an Ethernet-only part?
Yes. NVIDIA lists the MMS1V50-WM for Ethernet (400GBASE-FR4) use. For InfiniBand use the NDR / XDR qualified version of the same family.
Is the MMS1V50-WM compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with QSFP-DD 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 MMS1V50-WM?
Connector shown as MPO in NVIDIA's page title but FR4 is normally duplex LC; we confirm before dispatch.
Is your MMS1V50-WM 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 MMS1V50-WM price in India and how do I order?
The NVIDIA Mellanox MMS1V50-WM 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 980-9I160-00W000), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
