AI-generated summary
For £27.37 ex-VAT for a 1m 10G SFP+ DAC, this is the kind of “just make it work” cable that’s hard to beat—especially if you’re linking two like-for-like SFP+ ports on the same rack. Copper DACs are typically the most reliable and cost-effective way to get 10GbE short reach without paying for optics or extra power. If you’ve got a Switch-to-server, Switch-to-NAS, or top-of-rack tidy-up where 1m is enough, this is a sensible buy and usually saves hassle compared to more complex fibre setups.
That said, I wouldn’t stretch your expectations. Direct attach is unforgiving—wrong transceiver compatibility, power/feature quirks, or simply needing more reach will turn a cheap win into downtime. Also, “compatible” DACs are great until you hit a picky switch model that only whitelists certain modules; if you’re in a regulated environment or have older networking gear, it’s worth sanity-checking against what your switch/server vendor actually supports. Overall: buy it if your link is short and you’ve verified SFP+ DAC compatibility; skip it if you need longer distance, have known “compatibility sensitive” hardware, or you’re trying to standardise optics across mixed vendor ecosystems.
