Product Overview

AI-generated summary

For £42.18 ex-VAT, this is the kind of “get it working now” copper DAC you buy when you know the two ends are close enough for 10G over twinax. StarTech’s uncoded/breakout style tends to suit straightforward lab, staging, and short-reach rack-to-rack links where you don’t want to mess about with optics, power, or flaky transceiver compatibility. In day-to-day reseller terms: if your switch/server ports support it cleanly, DACs like this are usually excellent value—lower latency, no optics to fail, and you avoid the ongoing cost and downtime of transceivers.

That said, I’d only buy it confidently if you’ve already confirmed link compatibility with your exact switch/router and SFP+ implementation. “Uncoded compatible” can be fine in practice, but some kit is pickier than others, and passive DACs can be unforgiving if the link budget is tight. If you’re planning anything beyond a typical short run (or you’re unsure about support), you’ll be happier spending a bit more on a known-good, matched option—or moving to optics where range/compatibility headaches are reduced. For a staging room or a clean 5m intra-rack/top-of-rack setup, it’s a sensible buy; for unknown/iffy environments, it’s a gamble.
