What is the NVIDIA Mellanox MMA1B00-C100_B?
The MMA1B00-C100_B 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 maximum distance of the MMA1B00-C100_B?
NVIDIA specifies the MMA1B00-C100_B for up to 100 m on OM4 (70 m on OM3) multimode fiber.
Which fiber and connector does the MMA1B00-C100_B need?
The MMA1B00-C100_B 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-C100_B 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 MMA1B00-C100_B?
Build variant; current equivalent MMA1B00-C100D.
Is your MMA1B00-C100_B 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-C100_B price in India and how do I order?
The NVIDIA Mellanox MMA1B00-C100_B 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.
