X65406: frequently asked questions
What is the NVIDIA Mellanox X65406?
The X65406 is a QSFP28 100GBASE-CWDM4 module from NVIDIA's LinkX range for 100 Gbps Ethernet links. It plugs into a QSFP28 (or QSFP56) port on an NVIDIA / Mellanox switch, adapter or DPU and is used for 100GbE leaf-spine fabrics, EDR InfiniBand HPC clusters, storage and data-center interconnect.
What is the NVIDIA SKU for the X65406?
NVIDIA's current ordering number for the X65406 is 980-9I63F-00CM00. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN X65406. They are the same module; quote either and we will match it.
What is the maximum distance of the X65406?
NVIDIA specifies the X65406 for up to 2 km on single-mode fiber.
Which fiber and connector does the X65406 need?
The X65406 uses a Duplex LC connector on single-mode fiber (OS2), at 1310 nm band (CWDM4, 4 lanes). Both ends of the link must use the same optical standard.
Is the X65406 compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with QSFP28 (or 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.
Anything to check before ordering the X65406?
NVIDIA lists its lifecycle as 'Preliminary' in firmware release notes.
Is your X65406 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 X65406 price in India and how do I order?
The NVIDIA Mellanox X65406 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 980-9I63F-00CM00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
