Lightwin 10G SFP+ Direct Attach Copper Cable, 1m, Passive, 30AWG, MSA LWO-DAC-SFPP-1M

For short-reach 10 Gigabit links, this Lightwin passive DAC cable removes the cost and latency of optical transceivers while keeping the plug-and-play simplicity of a fixed assembly. The LWO-DAC-SFPP-1M pairs two SFP+ connectors with a 1-meter 30AWG copper twinax core, delivering full 10GbE throughput at a fraction of the power draw of active alternatives.

Highlights

• Passive Direct Attach Copper (DAC) design – no signal processing, minimal latency, and under 0.5W per end typical
• MSA-compliant SFP+ connectors on both ends for universal fit in switches, NICs, and servers
• 30AWG copper conductors with 100 Ohm impedance, tuned for 10G Ethernet and Fibre Channel
• Hot-swappable and SFF-8431/8432 compliant for reliable operation in dense racks
• Flexible PVC jacket and 1m length ideal for top-of-rack to server or adjacent switch links

In daily use

Installation is tool-free: the cable clicks into any standard SFP+ cage and is recognized immediately by the host. Because it is passive, there is no firmware, no heat sink, and no configuration – just a clean 10G link. The 1-meter reach is sized for direct connections between a top-of-rack switch and the server below it, or between two switches in the same cabinet. The 30AWG wire keeps the assembly thin and easy to route without blocking airflow, while the PVC jacket resists abrasion during moves and changes.

Final note

When every watt and every microsecond counts, a passive DAC like the LWO-DAC-SFPP-1M is the most efficient way to close a 10G link inside the rack – no optics, no surprises, just copper.
