AI-generated summary
For £315.26 ex-VAT, this AddOn SFP28 25GbE SR module is only a sensible buy if you’re buying it for the right kind of links: short, multimode runs where you’re happy using LC cabling and you don’t want to pay enterprise-transceiver pricing. In the real world, these are typically the “replace like-for-like” parts that keep switches and routers talking without drama—especially if your existing optics are already 850nm multimode. If you’ve got a datacentre patching environment and you know you’re staying within the practical reach for multimode, it’ll do the job and the price is reasonable compared to many branded options.
Why you might *not* buy it: if you’re not sure your switch supports third‑party optics (or you’re dealing with strict vendor monitoring/compatibility), you can end up with annoying “no link” or optics-threshold issues. Also, if your cabling plan is anywhere near the upper end of multimode distance, you’ll want to measure/confirm; don’t assume the headline reach is what you’ll reliably get in your specific fibre plant. This is best for cost-conscious teams who can validate compatibility with their exact switch model and have multimode fibre in place.
