Lightwin 25G SFP28 na SFP28 Direct Attach medený kábel, 3m, kompatibilný s HP Aruba (LWO-DAC-SFP28-3M-HPE)

For data centers and enterprise networks that demand reliable 25 Gigabit Ethernet links without the cost and complexity of optical transceivers, this Lightwin passive direct attach cable delivers a ready-to-use copper twinax connection between SFP28 ports. The 3-meter length is ideal for top-of-rack to server or switch-to-switch interconnects, while full compatibility with HP Aruba SFP28 and XFP interfaces ensures seamless integration into existing infrastructure. Unlike active optical cables, this passive DAC consumes less than 0.5W, helping to reduce overall power and cooling requirements in high-density deployments.

Highlights

• 25 Gbps data rate for high-performance 25GbE links
• Passive twinax copper construction—no power draw, no lasers
• Hot-swappable SFP28 connectors on both ends
• Compliant with SFF-8402 and IEEE 802.3by standards
• 3-meter length for flexible rack-level cabling

In daily use

Simply plug the cable into any compatible HP Aruba switch, server adapter, or network card with SFP28 ports. The cable is immediately recognized and begins passing traffic at full 25 Gbps line rate. The PVC jacket and robust strain relief withstand frequent re-cabling and tight bends in crowded racks. With an operating temperature range of 0°C to 70°C, it performs reliably even in warm aisle environments. Because it is a passive component, there is no firmware to update, no configuration to manage, and no additional power budget to allocate—just a dependable physical link.
