Product Overview

AI-generated summary

For £29.66 ex-VAT on a 2m 10GbE SFP+ copper DAC, this is one of those “sensible, boring” purchases that usually makes sense if you already have the right SFP+ ports. In day-to-day rack life, direct-attach copper is a lot less hassle than optics: lower cost, no power-hungry optics, and fewer moving parts. If you’re linking two switches within a short distance (or a switch to a server/ToR), this will typically come up fast in the real world and just work—especially for lab runs, staging, and straightforward production topologies.

That said, I’d buy this only if you’re confident your transceivers and switch firmware are happy with third-party DAC/cable assemblies. Some vendors are picky and you can end up with “it negotiates, but not reliably” or it simply won’t come up without the exact compatible part set. Also, 2m is a constraint—if your cable run is even slightly longer, you’ll be happier budgeting for the right optics instead of stretching copper and troubleshooting signal margins. For anyone who wants a cheap, short-reach 10GbE link and understands the compatibility angle, it’s good value; for environments with strict vendor optics/cable validation, I’d be more cautious.
