Product Overview

AI-generated summary

For £63.79 ex-VAT, this AddOn Cisco-compatible SFP+ for 10GbE with SR optics is the kind of “get it working without paying Cisco tax” purchase that makes sense in a lot of UK SMB and mid-market wiring closets. If you’ve already got multimode fibre run (typical in enterprise buildings) and your switch/router supports 10GBase‑SR, this is a solid value option—especially for spare transceivers, replacements that come up unexpectedly, or keeping costs down on non-critical links. In day-to-day use, the win is mostly practicality: pop it in, the link comes up, and you move on.

That said, I wouldn’t treat “compatible” as a guarantee of zero hassle. Some Cisco platforms are picky about optics/authentication; if your switch doesn’t like third-party modules, you can end up with warnings, limited diagnostics, or ports that don’t behave consistently. Also, it’s SR, so it’s only appropriate for shorter multimode runs—if you’re anywhere near the edge of your fibre budget, you’ll want to confirm the link performance rather than assume.

**Who should buy:** buyers with working multimode infrastructure who want cheap, reliable spares or replacements, and who have tested third-party optics before (or at least have a way to swap quickly if it won’t play nicely). **Who should skip:** teams running mission-critical links on gear known to be strict with optics, or anyone using single-mode/missing clear fibre specs—those are the situations where it’s better to pay more for optics that will be unquestionably accepted.
