DAC Cables

Direct Attach Copper (DAC) cables are factory-terminated twinax assemblies that integrate transceiver-style connectors such as SFP/SFP+, SFP28, QSFP+, QSFP28, QSFP-DD and OSFP at both ends, creating a cost-effective, zero-power electrical link for short-reach, high-speed networks.

Philipsun supplies a broad Direct Attach Copper Cable that covers data rates from 1 Gb/s to 400 Gb/s, reach options up to 10 m, and breakout formats (1-to-2, 1-to-4, 1-to-8) for flexible port aggregation. Each cable uses26- to 30-AWG shielded passive twinax conductors, complies with IEEE 802.3 and all relevant SFF or MSA specifications, and is verified to a bit-error rate of ≤ 1 × 10⁻¹². Typical latency is under 5 ns while link power remains below 0.5 W, ideal for switch, server and GPU interconnects in dense racks.
