AI-generated summary
At £45.10 ex-VAT for a 1m 25G SFP28 direct-attach cable, this is one of those “works great, but don’t buy it like it’s a generic accessory” purchases. If you’re using TP-Link Omada gear in a short-reach setup (usually between adjacent switch ports/racks) it’s a sensible way to avoid paying for optics and transceivers when you don’t need long-distance cabling. In day-to-day deployments, the big win is simplicity: you get a clean, reliable link without faffing around with additional optics modules and lead times.
That said, I wouldn’t buy this unless you’re confident about the exact distance and port compatibility in your rack layout. If there’s any chance you’ll need a longer run, you’ll be swapping hardware rather than “future-proofing” it, and you’ll likely end up spending twice. Also, direct-attach cables can be a bit fussier if your network has more demanding cabling environments (tight bends, poor handling, etc.), so buy it for tidy, well-managed installs. Who should buy: teams deploying Omada switches locally where 25G over short distances is the goal. Who shouldn’t: anyone expecting to reuse it across different distances or mixing platforms—optics choices get messy fast.
