Product Overview

AI-generated summary

At **£32.98 ex-VAT**, this is the kind of SFP-to-RJ45 “just make it work” module you buy when you’ve got a switch with spare SFP ports and you need **cheap, 1G copper reach** without rewiring everything. The appeal is simple: you can drop it into an SFP cage and run to a **Cat5e/Cat6** patch lead for short-to-medium distances, which is ideal for patch panel rollouts, access switches, or small server-room links where power and optics costs aren’t worth the faff. If your environment is mostly stable, and you’re not trying to standardise a whole datacentre with strict vendor optics policies, it’s good value.

The downside is also typical for these compatibility modules: **they can be picky** about switch models, firmware, and transceiver compatibility settings. I’d be cautious if you’re buying for a production network where you can’t risk “it works in one switch but not another” moments—especially if your vendor uses tight optics verification. If your switch supports third-party copper SFPs reliably, it’s a sensible buy; if you’re not sure, I’d rather see you **confirm compatibility with your exact switch model** (or buy from the same brand the switch vendor expects) before you commit.
