Dell Networking Cable, SFP+ to SFP+, 10GbE, Copper Twinax Direct Attach Cable, 1Meter

The Dell Y5DFK is a one meter SFP+ to SFP+ copper twinax direct attach cable that creates a dependable 10-Gigabit Ethernet link between Dell servers, switches, and storage systems. It is a practical choice for short-reach connections inside a rack or between adjacent racks, where speed matters but the distance does not justify the cost of optical transceivers.

Because the cable uses passive copper twinax technology, it draws very little power and adds almost no latency. Data center teams who want to lower operating costs while keeping performance high will appreciate this balance. The twinax design also helps reduce crosstalk, so signal integrity stays strong even in dense networking environments.

Installation is straightforward. The hot-pluggable SFP+ connectors click into place without tools, letting administrators swap or add links in seconds during maintenance windows or rapid scale-outs. Each end is coded for Dell interoperability, so the cable negotiates automatically with compatible Dell networking gear and reports accurate diagnostics to management software.

Use this cable when you need a quick, reliable, and cost-efficient path for traffic between a top-of-rack switch and the compute or storage nodes it serves. It is equally at home in enterprise server rooms, edge deployments, and lab setups where consistent 10GbE performance and trusted Dell support are priorities.
