AI-generated summary
For £79.58 ex-VAT, this Lenovo-branded SFP+ SR (850nm) module is a pretty solid “keep the switch running” buy—*if* you’re using it in the right kind of multimode setup. The SR 850nm ones are designed for short runs, so they’re ideal for typical data-closet / rack-to-rack fibre inside buildings. If you’ve got Lenovo switching gear that already expects Lenovo/compatible transceivers, this is the kind of straightforward part that usually avoids the annoying “it links but doesn’t behave” phase some third-party optics can cause.
I wouldn’t buy it if you’re trying to push it farther than your existing multimode cabling supports, or if you’re not sure what fibre type you’re on (single-mode vs multimode). Also, if you’re mixing brands or buying optics for a large rollout, you should sanity-check that your specific switch model plays nicely with third-party optics—brand-matched modules tend to be the lowest-drama option. Overall: good value for an in-house, short-range need on Lenovo equipment; waste of money if your link distance or fibre type doesn’t match what “SR 850” implies.
