25G-SFP28-L-SR: frequently asked questions
What is the NVIDIA Mellanox 25G-SFP28-L-SR?
The 25G-SFP28-L-SR is an SFP28 25GBASE-SR module from NVIDIA's LinkX range for 25 Gbps Ethernet links. It plugs into an SFP28 (or SFP56) port on an NVIDIA / Mellanox switch, adapter or DPU and is used for 25GbE server access, leaf-spine fabrics and 10G-to-25G migrations on ConnectX adapters and Spectrum switches.
What is the maximum distance of the 25G-SFP28-L-SR?
NVIDIA specifies the 25G-SFP28-L-SR for up to 70 m on OM3 and 100 m on OM4 multimode fiber.
Which fiber and connector does the 25G-SFP28-L-SR need?
The 25G-SFP28-L-SR uses a Duplex LC connector on multimode fiber (OM3/OM4), at 850 nm. Both ends of the link must use the same optical standard.
Is the 25G-SFP28-L-SR compatible with my NVIDIA / Mellanox switch or adapter?
It works in NVIDIA and Mellanox platforms with SFP28 (or SFP56) 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 25G-SFP28-L-SR still available?
NVIDIA has marked the 25G-SFP28-L-SR legacy / end-of-life, so it is no longer in regular production. Next Gen Networks sources genuine new and surplus stock on request. Same module as CX-T-25G-SFP28-L-SR. Current NVIDIA equivalent: MMA2P00-AS. Tell us the quantity and we will confirm availability, or suggest the current NVIDIA equivalent.
Is your 25G-SFP28-L-SR 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 25G-SFP28-L-SR price in India and how do I order?
The NVIDIA Mellanox 25G-SFP28-L-SR 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.
