About the NVIDIA Mellanox MMS1C00-CMLC
The NVIDIA Mellanox MMS1C00-CMLC is a hot-swappable QSFP28 100G PSM4 optical transceiver for 100 Gbps Ethernet links over single-mode fiber, with a 4 × duplex LC pigtail interface and reach of up to 2 km SMF. It is the MMS1C00 100GbE PSM4 module supplied pigtailed to four duplex LC connectors, so the fiber is factory-attached instead of plugging into a front-panel MPO port. PSM4 optics use four parallel single-mode lanes over an MPO-12 single-mode trunk, so one 100G link can also be split into 4 × 25G single-mode links. Typical uses: 100GbE leaf-spine fabrics, EDR InfiniBand HPC clusters, storage and data-center interconnect.

MMS1C00-CMLC: frequently asked questions
What is the NVIDIA Mellanox MMS1C00-CMLC?
The MMS1C00-CMLC is a QSFP28 100G PSM4 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 MMS1C00-CMLC?
NVIDIA specifies the MMS1C00-CMLC for up to 2 km on single-mode fiber.
Which fiber and connector does the MMS1C00-CMLC need?
The MMS1C00-CMLC uses a 4 × duplex LC pigtail connector on single-mode fiber (OS2), at 1550 nm (4 parallel lanes). Both ends of the link must use the same optical standard.
Is the MMS1C00-CMLC 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 MMS1C00-CMLC still available?
NVIDIA has marked the MMS1C00-CMLC legacy / end-of-life, so it is no longer in regular production. Next Gen Networks sources genuine new and surplus stock on request. Pigtailed legacy part; stock on request. Tell us the quantity and we will confirm availability, or suggest the current NVIDIA equivalent.
Is your MMS1C00-CMLC 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 MMS1C00-CMLC price in India and how do I order?
The NVIDIA Mellanox MMS1C00-CMLC 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.
