Product Overview

AI-generated summary

If you’re looking at this, you’re probably trying to keep an existing HPE switch/fibre setup going without paying the “proper” HPE tax. For that job, this StarTech-compatible SFP is a sensible value buy: it’s a multi‑mode, 1GbE SX optic intended for LC 550m-style links, and the DDM support is a genuinely useful extra in day-to-day operations (monitoring optics before they become downtime). The fact it’s sold as a 10-pack is where the economics usually win—ideal if you’re standardising spares or rolling out multiple ports.

That said, it’s not a universal “safe buy” for every environment. Compatible optics can be picky about firmware/port behaviour and vendor expectations, so only choose this if you’ve already confirmed it works in your exact HPE models (1400/1700/1820) and your cabling plan (multi‑mode characteristics, patch leads, cleanliness). Also, £249.25 ex‑VAT for 10 optics is fair, but not a bargain you should “blindly” stock—if you only need one or two, unit pricing can make it less compelling versus buying one verified option.

**Who should buy:** anyone running those specific HPE switches on multi‑mode fibre who wants reliable optics with monitoring and sensible spare capacity. **Who should avoid:** teams without confirmed compatibility, or anyone planning long-term migration where they’d rather standardise on a single vendor’s optics to reduce troubleshooting. If your network is stable and you can validate compatibility, this is a pragmatic cost saver; if you can’t, you’ll be paying in time when optics don’t negotiate cleanly.
