Lenovo 7Z57A03547 InfiniBand/fibre optic cable 5 m QSFP28 Blue

Product Overview

AI-generated summary

At £1,256.84 ex-VAT for a 5m Lenovo-branded InfiniBand/fibre cable, this is one of those purchases you *only* make when you already know the port/cabling standard you’re working to. The big question isn’t “is the cable good?”—it’s whether it matches your switch/NIC optics and InfiniBand setup end-to-end. In practice, for most standard data centre runs, a correctly specced certified fibre patch lead will do the job just as well. Where this specific Lenovo part can be worth the money is in environments where you want tight vendor compatibility, fewer finger-pointing moments during support calls, and you’re replacing like-for-like in an existing Lenovo stack.

Who should buy it: teams running InfiniBand over QSFP28 optics with strict compatibility requirements (or contracts/support agreements) and people who’d rather pay extra than risk “works on my bench” uncertainty. Who shouldn’t: anyone just connecting general-purpose links, anyone without confirmed compatibility for the exact InfiniBand/QSFP28 optics type, or buyers hoping to save money by trial-and-error—this price makes that a bad bet. If you tell me what you’re connecting (switch/NIC model or at least the optic type), I can sanity-check whether paying for a Lenovo-branded cable at this level is genuinely justified.
