Lenovo 7Z57A03541 InfiniBand/fibre optic cable 3 m SFP28 Blue

Product Overview

AI-generated summary

At £469.90 ex-VAT for a 3 m Lenovo-branded InfiniBand/fibre patch lead, this is very much a “buy it if you’re sure” item. The price feels premium compared with generic optics/cabling you might find for standard networking, but that’s usually because you’re buying something tightly aligned to a specific IB stack and vendor ecosystem. If you’ve got an existing Lenovo InfiniBand setup and you’re trying to keep change-control simple (known compatibility, predictable performance, less arguing with support), it can be good value.

Who should buy: data centre teams running InfiniBand where short-reach interconnects are part of a supported, vendor-managed environment—especially if you want a clean replacement for an existing link and you don’t want to gamble on third-party compatibility. Who should think twice: anyone trying to “test the waters” for connectivity, or teams that are happy to validate optics/cabling themselves and would rather spec from cheaper equivalents. If you’re not already deeply in Lenovo/InfiniBand, the cost won’t feel justified; spend time on compatibility checks first, because a wrong cable type for the fabric or optics expectations is an expensive way to learn.
