Lightwin 25G SFP28 to SFP28 Direct Attach Copper Cable 0.5m LWO-DAC-SFP28-0.5M

Modern data centers demand high-speed, low-latency connections between servers and switches, but optical transceivers can be costly and power-hungry. The Lightwin LWO-DAC-SFP28-0.5M Direct Attach Copper (DAC) cable solves this by delivering 25 Gigabit Ethernet over a short 0.5-meter passive copper link, eliminating the need for separate optics and reducing both cost and complexity.

Who is it for

This cable is ideal for network engineers and data center operators who need to connect SFP28 ports on servers, switches, and storage devices within a rack or adjacent racks. It is perfect for 25GbE deployments in enterprise and cloud environments where short-reach, high-density interconnects are required.
