Product Overview

AI-generated summary

If you’ve got short-reach SFP+ connections to make between two adjacent switches/servers, this sort of Cisco-branded DAC (twinax) is a sensible, low-hassle buy. The main real-world advantage is reliability and simplicity: no finicky optics alignment, no need to worry about compatibility beyond “are these ports actually SFP+?” For the £50.98 ex-VAT price, it’s especially reasonable when you’re filling a couple of links at 1m and you want something that “just works” in Cisco-centric kit (2960/2960G/2960S/Nexus 9k/UCS 6140 etc.).

That said, I wouldn’t buy it if you need longer runs or if you don’t know for sure the far end is expecting SFP+ copper DAC rather than fibre. Twinax is distance- and signal-sensitive, and the “right cable” matters; if you’re going beyond that typical short-reach window, you’ll either be stuck with poor link quality or forced to switch media. Also, if you’re doing a big volume project, DAC pricing can vary wildly—worth checking whether a compatible third-party DAC would land materially cheaper for the same link length.

**Who should buy:** teams running short links in a data centre rack with Cisco networking where adjacent devices need fast, dependable 10GbE-style connectivity. **Who shouldn’t:** anyone chasing longer distances, mixed/unknown transceiver compatibility, or buyers who aren’t confident they’re matching SFP+ copper expectations.
