FAQ
The SFP to SFP Passive Direct Attach Copper (DAC) Cable is a cost-effective and reliable short-reach interconnect solution designed for 1G to 4.25Gbps networking applications. It provides a direct electrical connection between SFP ports, eliminating the need for optical transceivers and reducing overall system cost and power consumption.
Built with 30AWG high-quality copper twinax construction, this DAC cable ensures stable signal transmission for short-distance links in data center and enterprise environments. It is widely used for switch-to-switch and switch-to-server connections where low latency, simplicity, and efficiency are required.
