Product Overview

AI-generated summary

At £63.79 ex-VAT, this AddOn 10GbE SFP+ SR module is the kind of budget option that makes sense *if* your network is straightforward and you’re buying in for spares. For the “classic” short‑reach multimode use case (typical datacentre patching), these usually work perfectly well and give you a cost-effective way to light up ports without paying Cisco-brand pricing. If you’ve got a mixed-vendor setup but you’re using the same standards for optics, this is a sensible value play—especially for fault tolerance (keeping a couple spares in the rack).

That said, I wouldn’t buy a pile of them unless you’ve validated compatibility with your exact switch/port firmware expectations. Clone/compatible optics can be picky: you may get “works today” but with quirks like demanding a specific transceiver configuration, occasional monitoring differences, or stricter DOM/labeling behaviour on certain platforms. For serious uptime environments, I’d still treat these as “good but test first” optics—buy one for a pilot, confirm link stability and throughput, and check that your management/threshold alerts behave as expected. If you can’t do that, or you need the lowest-risk optics for mission-critical links, the extra cost of OEM modules may be worth it.
