CX-T-100G-QSFP28-MSR4: frequently asked questions
What is the NVIDIA Mellanox CX-T-100G-QSFP28-MSR4?
The CX-T-100G-QSFP28-MSR4 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 CX-T-100G-QSFP28-MSR4?
NVIDIA specifies the CX-T-100G-QSFP28-MSR4 for up to 70 m on OM3 and 100 m on OM4 multimode fiber.
Which fiber and connector does the CX-T-100G-QSFP28-MSR4 need?
The CX-T-100G-QSFP28-MSR4 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 CX-T-100G-QSFP28-MSR4 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.
Is the CX-T-100G-QSFP28-MSR4 still available?
NVIDIA has marked the CX-T-100G-QSFP28-MSR4 legacy / end-of-life, so it is no longer in regular production. Next Gen Networks sources genuine new and surplus stock on request. Cumulus Express part (Mellanox OPN 100G-QSFP28-M-SR4). Current NVIDIA equivalent on request. Tell us the quantity and we will confirm availability, or suggest the current NVIDIA equivalent.
Is your CX-T-100G-QSFP28-MSR4 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 CX-T-100G-QSFP28-MSR4 price in India and how do I order?
The NVIDIA Mellanox CX-T-100G-QSFP28-MSR4 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, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
