Product Overview

AI-generated summary

For £35.93 ex-VAT, this is the kind of SFP-to-RJ45 module you buy when you just need “it to light up and work” for a short 1G copper link. It’s a sensible choice if you’ve got compatible HPE switch ports (your listed models are the key) and you’re trying to avoid paying the higher price for an official module. In day-to-day terms, if you’re doing normal Cat6/Cat5e runs up to around 100m, this should behave like a straightforward copper handoff—no drama, just connectivity.

That said, I’d only recommend it if your environment is low-risk and you’re buying for practical uptime, not for maximum compatibility guarantees. Third-party compatible SFPs can be perfectly fine, but you can sometimes run into issues like picky vendor firmware behaviour, flapping negotiations, or that annoying “unsupported transceiver” alert—even when the link eventually comes up. If this is mission-critical or you’re standardising across a large fleet, it’s worth confirming it’s been validated on your exact switch firmware and port type before you scale.

**Who should buy:** IT teams topping up spare parts for 1G copper links on supported HPE switches, where savings matter and cabling is solid. **Who shouldn’t:** anyone deploying this as a “universal” replacement across mixed hardware, or environments that can’t tolerate compatibility/diagnostic surprises.
