Lightwin 10G SFP+ Direct Attach Copper Cable, 3m, Passive Twinax, 10GbE, MSA Compliant, Hot-Swappable, Low Power LWO-DAC-SFPP-3M

The Lightwin LWO-DAC-SFPP-3M is a high-performance Direct Attach Copper (DAC) cable that delivers 10 Gigabit Ethernet connectivity over a 3-meter passive twinax assembly. Ideal for short-reach, high-density interconnects in data centers and enterprise networks, this cable provides a reliable, low-latency, and energy-efficient alternative to optical transceivers. With SFP+ connectors on both ends, it plugs directly into compatible switch, router, and server ports, eliminating the need for separate transceivers and reducing both cost and power consumption. The cable is fully MSA compliant, ensuring interoperability with a wide range of networking equipment from major vendors.

Advantages

Engineered for performance and ease of use, this DAC cable offers several key benefits:

• Cost-Effective: Eliminates the need for two SFP+ transceivers and fiber patch cords, significantly lowering total cost per link.
• Low Power Consumption: Passive design draws less than 0.5W, reducing energy costs and thermal load in dense racks.
• Low Latency: Direct copper connection provides near-zero latency, ideal for high-frequency trading, HPC, and storage applications.
• Plug-and-Play: Hot-swappable and pre-terminated; simply insert into SFP+ ports and the link is established—no configuration required.
• Durable Construction: 24 AWG twinax copper conductors with PVC jacket ensure signal integrity and mechanical robustness.

Suitable for

This cable is perfect for short-distance 10GbE connectivity in a variety of environments:

• Top-of-rack (ToR) switch to server connections in data centers
• Server-to-server clustering and high-availability setups
