About the MFS1S00-H035V

The NVIDIA Mellanox MFS1S00-H035V is a 35-meter QSFP28 active optical cable for 200Gb/s InfiniBand HDR systems. Note that this SKU uses the QSFP28 form factor rather than QSFP56 — verify your switch and adapter port types before ordering. NVIDIA issued an End-of-Life notice for this variant in March 2022. Our stock of 900 factory-sealed units is among the last available new-in-box supply. At $140 per unit (up to 90% below retail), this represents exceptional value for data centers maintaining existing QSFP28-based HDR infrastructure.

Typical Use Case

The 35m QSFP28 variant is deployed in mid-scale HPC clusters and research computing environments where the spine-to-leaf distance is 30–40 meters and the infrastructure uses QSFP28 port switches such as earlier-generation Mellanox SB7800 series.

New In Box vs. Compatible — Why It Matters

NVIDIA Quantum HDR switches and ConnectX-6/7 adapters perform firmware-level cable authentication at link initialization. Genuine OEM cables like the MFS1S00-H035V pass all NVIDIA firmware checks without modification, ensuring full 200G performance and BER compliance. Third-party compatible cables can trigger firmware warnings and cause intermittent link drops under sustained load.

Why Are Brand-New Cables Available at 90% Below Retail?

These 12,006 cables were purchased new by a large enterprise customer for a planned HDR InfiniBand fabric deployment. The project was cancelled before installation — the cables were never racked, never powered, never touched. They remain in their original NVIDIA Mellanox factory packaging, exactly as shipped from the manufacturer.

The result: genuine, factory-sealed NVIDIA Mellanox hardware available at project-liquidation pricing. This is a one-time inventory event. When these units are gone, new-in-box HDR cables at this price will not exist again.
