For £21.26 ex-VAT, this is the sort of “just get link up” SFP you’d pick when you’re trying to keep a rack running without paying big-brand prices. The single-mode 1GbE LX with LC and ~10 km reach is a very common spec for enterprise/campus links over fibre, so in the right environment it’s good value—especially if you’re swapping like-for-like optics and you don’t need anything exotic (or higher-speed upgrades). If you’ve got older switches/patch panels that already use 1310 nm LC single-mode, this should be an easy, low-cost fix for a dead port or a spare-in-a-drawer situation.
That said, I wouldn’t treat it like a universal “works with everything” module. Compatibility can be finicky with SFPs—some switch models are picky about vendor/EEPROM behaviour, and you can end up with ports that light but don’t negotiate reliably, or only partially support features like diagnostics. Before you buy, check that the switch manufacturer explicitly supports that module type (or at least that your exact switch model works with compatible SFPs). If you’re building a critical link and downtime is expensive, it’s worth verifying compatibility first; if it’s for a non-critical segment or you’ve got a fallback plan, it’s a sensible budget buy.
