£180.77 inc. VAT
AI-generated summary
This is one of those “nothing fancy, just works” Dell-compatible multi‑mode SFPs. If you’ve got a Dell switch/stack that already expects this type of module, £150.64 ex‑VAT is a fair price for reliability—especially because genuine/known-good optics usually save you the grief of intermittent link flaps that can happen with random third‑party replacements. For typical UK datacentre/core wiring between adjacent racks or moderate distances over OM links, it’s a solid, low-risk purchase.
I wouldn’t buy this if you’re trying to make multimode optics work on a setup that’s actually single‑mode, or if your network gear doesn’t explicitly play nicely with Dell-branded or Dell-certified SFPs (in some environments, compatibility filtering can be a time sink). Also, if you only need one or two ports and you’re price-sensitive, it’s worth shopping around specifically for “compatible” equivalents rather than defaulting to Dell—just don’t go bargain-basement unless you can verify they’re known stable in your exact switch model.
**Who should buy:** anyone with Dell switching and existing multimode fibre infrastructure who wants dependable optics without experimenting. **Who shouldn’t:** folks with unclear fibre type/distance requirements, or anyone trying to use it as a generic “any switch” solution.
