Product Overview

AI-generated summary

At £31.93 ex-VAT for a “Citrix compatible” 1Gb copper SFP, this is basically a budget way to get an extra RJ45 port without paying the mini-van pricing you sometimes see for branded optics. That said, the key question isn’t the label—it’s whether your switch supports this *specific* kind of copper SFP and whether it exposes link/DOM info the way your environment expects. In the real world, these cheap RJ45-SFPs often work fine for straightforward 1Gb connectivity (e.g., patching a switch to an office drop over Cat5e/6 up to ~100m), but they can be a bit more hit-and-miss with older firmware, strict compatibility checks, or setups that monitor optics details.

Who should buy it: teams with standard 1Gb over copper needs, clean Cat5e/6 runs, and switches that are known to accept third-party SFPs—especially if you’re trying to keep costs down on spare ports or temporary installs. Who should *avoid*: anyone relying on tight compatibility “green lights,” optical/module management features, or who has a switch model that is picky about optics. If you can, verify compatibility against your switch vendor’s tested list (or at least confirm it works with similar StarTech/3rd-party copper SFPs) before you stock up—because saving a few quid up front isn’t worth the hassle if you end up with link flaps or unsupported-module errors.
