At £91 ex-VAT, this looks like a pretty sensible “keep the lights on” purchase if you know exactly what you’re replacing. StarTech’s MSA-compliant approach is generally dependable for mixed-vendor environments, and the big practical win here is the BiDi angle: it lets you run 10G over a single fibre using a pair of wavelengths, which can be a lifesaver when you’ve only got one strand available in an existing duct or patch panel. If your current switch/router supports 10GBase-BX and you’ve already confirmed the upstream direction and LC interface match, then this is the kind of module that’ll slot in with minimal drama and do the job without you having to rework cabling.
Where I’d be cautious is the usual SFP+ gotchas: you *must* match the “upstream”/“downstream” behaviour for your link partner and ensure your optics pair is intended for BiDi on single-strand fibre at your target distance. Also, don’t expect this to be a bargain if you’re buying it “just in case”—SFP/optics compatibility is easy to get wrong, and when it is, it’s not a quick workaround. If you’re repairing one specific link with known requirements, it’s good value; if you’re trying to upgrade or retrofit without pulling specs for the existing transceiver pair, I’d hold off and verify first.
