StarTech.com Dell EMC SFP-10G-BX10-U Compatible SFP+ Module - 10GBASE-BX-U - 10 GbE Gigabit Ethernet BiDi Fiber (SMF)

Product Overview

AI-generated summary

At £20.77 ex‑VAT for a “compatible” 10GbE BiDi SFP+, this is the sort of bargain item that can absolutely make sense for a reseller’s toolbox—*if* your environment is already set up for single‑strand (BiDi) operation and your switching gear is picky-but-still-compatible. BiDi optics are great when you’re short on fiber cores or stuck with existing ducting where you only have one strand available. For straightforward point-to-point links or simple uplinks where the optics match the distance and wavelength your network expects, it can be a very cost-effective way to get 10GbE working without paying OEM prices.

That said, I’d be cautious because these “compatible” modules live and die by interoperability. Even if they work, you want to confirm platform compatibility and test for link stability, especially if the switch runs strict optics monitoring or has had headaches with third-party transceivers. Also, the category you mentioned (“privacy filters”) is… odd—make sure you’ve actually got the optics listing you think you’re buying, not a misfiled product page. If you need guaranteed behaviour in a production backbone with no time for testing, you’re usually better off with OEM-branded modules or a vetted, documented compatibility list. If you’re running lab gear, edge switches, or you can trial it quickly, this price makes it a sensible “try it and verify” purchase.
