Product Overview

AI-generated summary

For £40.57 ex-VAT, this is the kind of DAC you buy when you need short-range 10GbE links without paying the optics tax. In real deployments it’s great for patching between a switch and another switch/storage or a server NIC—especially where the distance is well within a typical rack-to-rack run. It’s passive (no power draw from the module side), so it’s a clean, low-fuss option for equipment that already supports SFP+ and is configured for 10GbE copper DACs.

That said, it’s not a “universal will work with anything” cable. Compatibility is very much “switches and optics admin reality”: some older firmware revisions or picky vendor implementations can be touchy with third-party DACs, and if you’re aiming at HPE Firepower gear specifically you’ll want to confirm it’s been validated/works with your exact model/firmware. If you’re in a sensitive environment where downtime is expensive, I’d personally insist on a quick compatibility check (or buy a short spare) before rolling it broadly. If you just need reliable copper within rack distance, though, this is good value for a straightforward 10GbE connection.
