DAC Cable or Direct Attach Copper Cable is a high speed, twinax copper cable with transceiver-style connectors on both ends, used for short-range, direct connections (up to ~10m) between servers, switches, and storage devices in data centers. Supporting 10G, 25G, 100G, 400G and other mainstream rates, it enables stable, low-latency transmission between switches, servers, storage devices and network equipment without additional optical modules.

Compared with fiber optic patchcord and optical tranceiver, DAC cables feature lower power consumption, faster deployment, higher anti-interference and more competitive cost, effectively reducing infrastructure investment and operation costs. Available in various mainstream including DAC cable and breakout DAC Cable with 10G SFP+, 25G SFP28, 100G QSFP28, 200G 200G QSFP56, 400G QSFP-DD and more, delivering reliable performance in short range interconnection.

Widely used in data center top of rack connections, cloud computing centers, enterprise server rooms, high performance computing clusters, 5G communications and storage area networks, DAC Cable provides stable, efficient and economical wiring solutions for high speed interconnection scenarios.
