22 Jun, 2026





£66.46 inc. VAT
AI-generated summary
For £55.46 ex-VAT, this looks like a sensible “get the link up” SFP+ for 10GbE over single-mode fibre at up to the stated reach, especially if you’re trying to keep spares costs down in a UK office/enterprise network. It’s MSA-style and includes DDM, which is exactly what most of us want day-to-day: the switch can typically read optical diagnostics, and troubleshooting is less of a guessing game when a fibre run or patch panel goes wrong. In practice, it’s a good fit for typical 10GbE switch-to-switch or switch-to-server links where you already have SMF and the distance isn’t pushing the limit.
That said, I’d only buy it if you’ve confirmed compatibility with your specific switch model. “MSA compliant” is helpful, but SFP acceptance can still be picky depending on the vendor and firmware, and “works in a lab” isn’t the same as “works in your chassis on Friday night.” Also, £55 for optics is budget-friendly—great—but it’s rarely the same as buying from the original OEM if you’re running a mission-critical core link. If you need maximum certainty, low return hassle, and long-term peace of mind, branded OEM optics can be worth the premium. If this is for non-core, planned runs with verified fibre, or you just need reliable 10GbE optics at sensible cost, this is a decent buy.
