Product Overview

AI-generated summary

For ~£84.67 ex-VAT, this StarTech-branded SFP28 is a pretty sensible buy **if you just need a straightforward, short-reach 25Gbps multimode optical link** and you’re not trying to push edge-case compatibility. The 100m/LC/MMF intent is exactly what it’s good at in real UK rack-and-corridor environments—think access switches to patch panels, or top-of-rack to server aggregation over existing OM3/OM4 runs where you’d rather not pay the premium for “named OEM only” optics. In practice, these third-party modules often behave fine as long as your switches don’t have overly fussy firmware/whitelist behaviour.

Why you might *avoid* it: if you’re in a shop with strict optics validation (some HPE environments can be picky), or you’re mixing optics across different switch families/vendors and want the lowest risk, this may be more hassle than it’s worth. Also, if you’re sitting near the distance limit or your fibre plant is messy (old patch cords, uncertain OM type, lots of bends), you’ll feel it sooner with optics than with copper.

**Who should buy:** UK IT resellers/MSPs and internal teams standardising on 25GbE over MMF at ~100m and who want good value without drama. **Who shouldn’t:** anyone who can’t afford even a small chance of “module not recognised” during rollout, or anyone whose fibre links are anything other than clean, known-good multimode.
