Lenovo 90Y9433 InfiniBand/fibre optic cable 5 m SFP+ Black

Product Overview

AI-generated summary

If you’re looking at the Lenovo 90Y9433, you’re probably doing proper, high-speed storage or HPC networking where InfiniBand or fibre are involved and you don’t want the faff of “will this third-party cable behave like the spec sheet says?”. For that use case, buying the Lenovo-branded lead at ~£154 ex-VAT for a 5 m run is defensible—especially in environments where uptime and vendor support matter, and where the cable’s compatibility is the whole point. This is the sort of thing you buy for a rack you can’t afford to troubleshoot for days.

That said, I wouldn’t buy it blindly just to “connect two things” if you’re not sure you actually need an InfiniBand/fibre SFP+ style interconnect. For many standard networking jobs, it’s easy to overspend because people assume “cable is cable”. Also, at this price, if you’ve got flexible requirements (shorter/longer run availability, known-good transceivers already in place, no strict support constraints), you may find better value from reputable-compatible optics/cables—assuming your vendor/controller won’t get twitchy about it. Bottom line: buy it if you’re matching a known InfiniBand/fibre setup and want low-risk compatibility; don’t buy it if you’re still figuring out what the system actually supports.
