Description
The 25G SFP28 Direct Attach Copper (DAC) Cable is a high-speed, passive copper interconnect designed for reliable and cost-effective 25Gbps Ethernet connectivity. Featuring SFP28 connectors on both ends, it supports data rates up to 25.78Gbps while providing a low-power, low-latency connection for compatible network equipment. The passive design eliminates the need for optical conversion, making it an economical solution for short-distance high-speed connections.
Available in lengths from 1m to 5m, this SFP28 DAC is optimized for high-density data center and server networking environments where short, direct connections are required. Its low insertion loss, low crosstalk, and low EMI characteristics help maintain signal integrity while supporting high port density and efficient rack-level connectivity.
