AI-generated summary
For £38.84 ex-VAT, this is a sensible buy **if** you’re trying to get an SFP+ port working with minimal fuss on a **bi-directional (BiDi) SMF** link. The value is real for patching infrastructure or expanding capacity without replacing switches/routers—especially in estates where the cabling is already there and you just need the right optics to match it. StarTech is generally dependable in day-to-day reseller deployments, and for short “get it back online” jobs, this is the kind of part that saves time and spend.
That said, I’d be cautious if you’re buying it as a “catch-all” optic. BiDi modules are **not interchangeable** with standard 10GBASE optics, and the whole thing lives or dies on correct fiber type and the **TX/RX direction pairing**. If you don’t already know your link is set up for BiDi on single-mode, you can waste money quickly. Also, privacy-filter category aside, this isn’t a security/privacy product at all—so double-check you’re selecting the right hardware for your network. Overall: **buy it if you know you need 10G BiDi SMF and you’ve got the right cable/fiber plan**; otherwise, spend a bit more time confirming compatibility first.
