If you’re connecting two switches/servers over a short-to-medium rack/cabinet link and you want something that just works, this StarTech 40G QSFP+ AOC lead is a sensible buy—especially at £89.62 ex-VAT. Active optical cables (AOC) are handy when you don’t want to mess about with optics, cleaning fibre connectors, or managing patch panels. They’re also typically more forgiving in everyday cable runs than bare fibre, and you get the convenience of “plug it in and go” for 40GbE QSFP+ direct attach-style use.
That said, I wouldn’t treat AOC as a universal replacement for every fibre scenario. If you need maximum long-term flexibility, easy troubleshooting, or you expect to reuse fibres across changing sites, a more traditional fibre + separate optics approach can be cheaper over time and easier to scale. Also, AOC cables are often less friendly for moving parts—once you’ve committed to that exact cable length and endpoints, upgrades can mean swapping the whole lead rather than just the optic. Buy this if you want low-hassle 40GbE between QSFP+ ports at around 7m; skip it if you’re building a broader cabling standard or you anticipate frequent endpoint changes.
