Lenovo 7Z57A03558 InfiniBand/fibre optic cable 3 m SFP28 Black

Product Overview

AI-generated summary

This is the kind of item you buy when you already know you’re in an InfiniBand/Fibre setup and you just need a reliable interconnect to get a link up, not when you’re “trying to be compatible”. At £58.10 ex-VAT for a 3m lead, it’s not outrageously priced, but it’s not the cheapest way to solve a problem either—so I’d only pay this if you’ve confirmed the exact interface type you need (SFP28 and the right active/optical/IB environment). If you’re mixing vendors or not 100% sure on the port/transceiver type, you can end up with cables that are technically plausible but operationally useless. In short: good if you’re matching like-for-like; annoying if you’re guessing.

Who should buy it: teams running InfiniBand fabric in the UK and needing spares for rack moves, repairs, or planned upgrades—especially if you want a Lenovo-branded part to minimise compatibility drama. Who shouldn’t: anyone trying to repurpose it for general networking (Ethernet) runs, or those hunting for “any fibre that fits” without validating the optics and host side. If your link budget and distance are already covered, this is a straightforward, dependable choice; if you haven’t validated that the SFP28/InfiniBand pairing is correct, I’d pause and check first.
