SPQ-CE-ER-CDFL-M: frequently asked questions
What is the NVIDIA Mellanox SPQ-CE-ER-CDFL-M?
The SPQ-CE-ER-CDFL-M is a QSFP28 100G ER4 module from NVIDIA's LinkX range for 100 Gbps InfiniBand 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 SPQ-CE-ER-CDFL-M?
NVIDIA's current ordering number for the SPQ-CE-ER-CDFL-M is 980-9I53X-00C000. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN SPQ-CE-ER-CDFL-M. They are the same module; quote either and we will match it.
What is the maximum distance of the SPQ-CE-ER-CDFL-M?
NVIDIA specifies the SPQ-CE-ER-CDFL-M for up to 40 km on single-mode fiber (with FEC; attenuation may be needed on short links).
Which fiber and connector does the SPQ-CE-ER-CDFL-M need?
The SPQ-CE-ER-CDFL-M uses a Duplex LC connector on single-mode fiber (OS2), at 1310 nm (LAN-WDM, 4 lanes). Both ends of the link must use the same optical standard.
Can the SPQ-CE-ER-CDFL-M be used on an Ethernet port?
NVIDIA qualifies the SPQ-CE-ER-CDFL-M for 100G ER4. Ethernet use is not listed for this part number; tell us the switch or adapter model and we will suggest the Ethernet-qualified equivalent from the same family.
Is the SPQ-CE-ER-CDFL-M 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 SPQ-CE-ER-CDFL-M?
Long-haul part; confirm link budget and FEC/attenuation with us before ordering.
Is your SPQ-CE-ER-CDFL-M 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 SPQ-CE-ER-CDFL-M price in India and how do I order?
The NVIDIA Mellanox SPQ-CE-ER-CDFL-M 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 980-9I53X-00C000), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
