Mellanox Technologies 3m QSFP Black InfiniBand Cable - Direct Attach Copper (DAC)

The Mellanox Technologies 3m QSFP Black InfiniBand Cable is a high-performance Direct Attach Copper (DAC) solution designed for demanding data center and high-performance computing (HPC) environments. This passive cable delivers reliable 40 Gb/s QDR connectivity over a 3-meter length, featuring QSFP connectors on both ends for seamless integration with Mellanox InfiniBand switches, HBAs, and other QSFP-compatible devices. Its robust copper construction and black jacket ensure durability and easy identification in dense cable runs.

Advantages

This cable offers a cost-effective and low-latency interconnect for high-speed networks. As a passive DAC, it requires no external power, consuming less than 0.5W per end, and supports hot-pluggable installation. The 3-meter length provides flexibility in rack configurations while maintaining signal integrity. Mellanox certification guarantees compatibility and performance in Mellanox-based infrastructures.
