About the MFS1S00-H050V
The NVIDIA Mellanox MFS1S00-H050V is a 50-meter QSFP56 active optical cable (AOC) designed for 200Gb/s InfiniBand HDR and 200GbE deployments. It is the most widely deployed long-reach cable in AI training clusters and HPC supercomputers, providing a cost-effective, high-density alternative to passive copper at distances beyond 5 meters.
Why 50m Is the Most Popular Length
In a typical fat-tree InfiniBand topology, spine-to-leaf connections span 40 to 60 meters when routing through raised floors and overhead cable trays. The 50m MFS1S00-H050V hits the sweet spot for most large-scale deployments — long enough to reach across a full data center row, short enough to avoid the premium pricing of the 80m and 100m variants. With 5,516 units in stock, we can fulfill full-rack and full-cluster orders immediately.
New In Box vs. Compatible — Why It Matters
NVIDIA's Quantum HDR switches and ConnectX-6/7 adapters perform firmware-level cable authentication at link initialization. While third-party compatible cables often pass basic link-up tests, they can trigger firmware warnings, fail BER (Bit Error Rate) certification, and cause intermittent link drops under sustained 200G load. Our MFS1S00-H050V units are genuine OEM — they will pass all NVIDIA firmware checks without modification.
EOL Status and Supply Context
NVIDIA issued End-of-Life notices for several MFS1S00-V series variants in 2022. While the H050V remains available through authorized channels, lead times from distributors have extended to 8–14 weeks. Our in-stock inventory ships same day, making this a critical source for data centers that cannot afford extended downtime or deployment delays.
