Lightwin 25G SFP28 to SFP28 Direct Attach Copper Cable, 5 m, Passive Twinax, 26 AWG, PVC Jacket LWO-DAC-SFP28-5M

Direct Attach Copper (DAC) cable delivering 25 Gbps over a 5-meter passive twinax link, engineered for high-density SFP28 interconnects in data centers and enterprise networks. This cable provides a low-latency, low-power alternative to optical transceivers, with a power draw under 0.5 W and hot-pluggable convenience for rapid deployment. The 26 AWG copper conductors and PVC jacket ensure reliable signal integrity and durability in demanding environments.

Advantages

Passive twinax construction eliminates active components, reducing power consumption to less than 0.5 W while maintaining full 25 Gbps throughput. The 5-meter length offers flexibility for rack-to-rack or server-to-switch connections without signal degradation. Hot-pluggable SFP28 connectors allow for quick installation and replacement without network downtime. Compliance with SFF-8402, SFF-8431, and SFF-8472 standards guarantees compatibility with a wide range of networking equipment.

Suitable for

• Data center top-of-rack to end-of-row server connections
• Storage area networks (SAN) requiring high-bandwidth, low-latency links
• 25 Gigabit Ethernet and InfiniBand EDR fabric interconnects
• Environments where power and cooling budgets are constrained
