StarTech.com MSA Uncoded Compatible 1m 10G SFP+ to SFP+ Direct Attach Breakout Cable Twinax - 10 GbE SFP+ Copper DAC 10 Gbps Low Power Passive Transceiver Module DAC

Product Overview

AI-generated summary

For £25.75 ex-VAT for a 1m direct-attach breakout in copper, this is the kind of “just get it working” DAC you buy when you’ve got short runs between like-for-like switches/servers and you don’t want to pay for optics and patching. Passive DACs are great value in the real world: lower latency, no optics hassle, and they’re simple to deploy. If you’re building or refreshing a small rack-to-rack setup (or within the same cabinet) and your end devices support the right SFP+ profile, it’ll do exactly what it says with minimal fuss.

The catch is compatibility. “MSA uncoded compatible” and “direct attach breakout” is one of those phrases that can mean “works with most gear” until it doesn’t—some switches/servers are picky about pinouts, power/threshold expectations, and how they treat “breakout” behavior. If you’re deploying at scale or for mission-critical links, I’d only buy this if you’ve verified compatibility with your specific model(s) or you’re comfortable swapping it out. For longer distances than typical short copper ranges, you’ll also start to see reliability drop-off, so it’s not a “set and forget” cable for anything beyond close runs.

**Who should buy:** teams with short, known-good SFP+ connections who want low-cost 10GbE copper without optics. **Who should avoid:** anyone unsure about SFP+ compatibility on their exact hardware, or anyone hoping it’ll rescue longer links—optics will be the safer purchase.
