Product Overview

AI-generated summary

For a straight 10GbE rack-to-rack link, this kind of passive DAC twinax is usually a sweet spot in the real world: it’s cheap, low-power, and it behaves predictably compared to fiber when you’re just trying to get connectivity working fast. At £32.58 ex-VAT for 3m, you’re paying a sensible amount for something that should “just work” for the typical short-reach use cases—think servers to switches in the same rack/cabinet or adjacent cabinets where you don’t need the extra expense (or fuss) of optics and patch leads.

Who should buy it: teams with Dell EMC SFP+ ports (and a matching expectation of passive DAC support) who have short copper runs and want to minimize total cost of ownership—especially if you’re standardising cabling and reducing power draw. Who should *not* buy it: anyone who’s trying to use it beyond the supported distance for their specific gear, or anyone mixing brand/model optics where compatibility isn’t guaranteed. Even though it’s marketed as “compatible,” the only real risk with these is link/compatibility behaviour on certain switch/SFP combinations—so if you’ve got critical links and strict change control, it’s worth validating in a lab or with a quick test before committing everywhere.
