Product Overview

AI-generated summary

For the money (£106.30 ex-VAT), this is the kind of 25GbE SFP28 you buy when you want “Cisco-like” compatibility without paying Cisco prices. The real-world win is that it’s aimed at short-reach multi‑mode deployments (data centre links, server-to-switch, and similar runs where fibre patching is already in place). If you’ve got supported Cisco Catalyst models listed and your cabling is multi‑mode with the right optics setup, it should slot in cleanly and do the job—no drama, no fiddling, just throughput you actually paid for.

That said, I wouldn’t buy it blindly if you don’t already know your optics and module pairing are consistent end-to-end. The most common failure mode with third-party transceivers is not “it doesn’t work at all,” but incompatibility quirks with specific switch software/operating modes, or misunderstanding the fibre type (multi‑mode vs single‑mode) and expected reach. For a reseller, I’d only recommend this if you can confirm the link design (fibre type, patching, and the far-end optics) and you’re using it in the supported Cisco ecosystem—otherwise you risk spending “cheap module” money to troubleshoot. Suitable buyers: teams refreshing port density on supported Catalyst switches where they want value and predictable operation on short multi‑mode links. Unsuitable: anyone running odd optics mixes, uncertain cabling standards, or long-reach requirements.
