SFP28 DAC Cable BlueOptics SFP28-DAC-3M-SS 3m Male/Male

The BlueOptics SFP28-DAC-3M-SS is a 3-meter direct-attach copper (DAC) cable with SFP28 male connectors on both ends, designed for 25 Gigabit Ethernet interconnects. Built for short-reach, high-bandwidth links, this cable provides a fixed, low-latency connection between compatible switches, servers, and network interface cards in data center and high-performance computing environments. The cable’s compact form factor and mechanical SFP28 plugs simplify installation in dense rack deployments.

Advantages

This SFP28 DAC cable offers predictable electrical performance for 25 Gbps links while avoiding the need for transceivers or separate optical modules. The integrated SFP28 connectors reduce component count and cabling complexity, and the 3 m length balances reach with low signal attenuation. The cable’s design supports reliable hot-pluggable connections and is suitable for high-density patching where space and port availability are limited.

Suitable for

• Short-reach 25 Gigabit Ethernet links between switches and servers
• Top-of-rack and end-of-row interconnects in data centers
• High-performance computing clusters and storage networks
• Direct connections between network interface cards and switches

How to use

Power off or follow hot-swap procedures recommended by your equipment vendor, then insert each SFP28 connector into the appropriate SFP28 port on your devices until it latches. Verify link status through device LEDs or management interfaces. For initial deployment, test link integrity and speed using network diagnostics or switch port statistics. If necessary, consult switch or NIC compatibility lists to confirm supported direct-attach cables.

Recommendations

The cable is intended for short-reach connections within racks or between adjacent racks. Avoid tight bends and excessive pulling on the cable; maintain the manufacturer’s minimum bend radius and route the cable to prevent mechanical stress. Use appropriate electrostatic discharge precautions when handling SFP28 connectors and follow your hardware vendor’s guidelines for hot-plugging and firmware compatibility checks.
