NVIDIA Mellanox DAC and Breakout Cables - Refurbished, Used, New

Best Selling

NVIDIA Mellanox LinkX direct attach copper (DAC) cables connect switch and adapter ports over short distances, usually within a rack, without separate optical transceivers. Passive DACs are the lowest-cost link, with almost no power draw or added latency. NetworkTigers sells straight and breakout DAC cables with SFP+, SFP28, QSFP28, QSFP56, QSFP-DD and OSFP ends, refurbished, used and new, and every cable is tested and working before it ships.

Breakout and splitter cables

A breakout cable splits one fast port into several slower links, for example one 100G switch port to four 25G servers.

Each listing gives the full part number, length, and Ethernet or InfiniBand use.

Which length do I need?

Measure the routed cable path, not the straight-line distance, and allow for cable managers. Passive copper reach falls as speed rises, so NVIDIA DACs run to a few meters at most at 100G and above. For longer runs, use active optical cables or transceivers.
