MMA1B00-C100D: frequently asked questions
What is the NVIDIA Mellanox MMA1B00-C100D?
The MMA1B00-C100D is a QSFP28 100GBASE-SR4 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 MMA1B00-C100D?
NVIDIA's current ordering number for the MMA1B00-C100D is 980-9I149-00CS00. Newer NVIDIA price lists, quotes and firmware support tables use this 980-/930- SKU, while older documents and most resellers use the legacy OPN MMA1B00-C100D. They are the same module; quote either and we will match it.
What is the maximum distance of the MMA1B00-C100D?
NVIDIA specifies the MMA1B00-C100D for up to 70 m on OM3 and 100 m on OM4 multimode fiber.
Which fiber and connector does the MMA1B00-C100D need?
The MMA1B00-C100D uses a MPO-12/UPC connector on multimode fiber (OM3/OM4), at 850 nm. Both ends of the link must use the same optical standard.
Is the MMA1B00-C100D 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.
MMA1B00-C100D vs MMA1B00-E100: which one for Ethernet, which for InfiniBand?
MMA1B00-C100D is the 100GbE Ethernet SR4. MMA1B00-E100 is the EDR 100 Gb/s InfiniBand SR4 (also 100GBASE-SR4 compliant). Use C100D on Spectrum / Ethernet ports and E100 on Switch-IB / Quantum EDR InfiniBand ports.
Does the MMA1B00-C100D support breakout?
NVIDIA lists 4 × 25G SR with an MPO-to-4×LC breakout, where the port supports splitting. Use the matching optics at the far end and a suitable splitter or breakout cable, and enable port splitting on the switch.
Is your MMA1B00-C100D 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 MMA1B00-C100D price in India and how do I order?
The NVIDIA Mellanox MMA1B00-C100D 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 980-9I149-00CS00), quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
