AI-generated summary
For £87.50 ex‑VAT, this is one of those “it’s not just a cable” purchases. A Lenovo-branded SFP+ optical lead is the right sort of thing when you’re plugging into a specific InfiniBand or compatible fibre environment and you want fewer headaches than with generic optics. In a UK data centre, the upside is reliability and supportability—if your switch/server stack is Lenovo-centric and you’ve already standardised on their optics ecosystem, it usually just works and you’re less likely to get weird link issues or compatibility dithering.
That said, I wouldn’t buy this purely because it’s “SFP+” and cheap-ish. If you don’t already know the cable length and type you need for your switch ports, or you’re mixing vendors (Lenovo switch ↔ non‑Lenovo optics/IB modules), you could end up paying for brand comfort when a more broadly compatible option would do the job. Also, if this is for occasional lab use, optical cabling tends to be overkill—copper or a different approach is often better value. Bottom line: buy it if you’re operating a supported Lenovo IB/fibre setup and want low-risk deployment; skip it if you’re still figuring out compatibility/length or you’re cobbling together a mixed hardware stack.
