DELL 470-ABQB InfiniBand/fibre optic cable 3 m QSFP28 4x SFP28 Black, Red

Product Overview

AI-generated summary

At £385+ ex‑VAT for a 3 m Dell-branded QSFP28-style InfiniBand/fibre cable (4x), this isn’t the kind of item you casually “grab just in case”. The cost usually only makes sense if you’re in an environment that’s already standardised on Dell networking/optics and you need guaranteed compatibility with minimal faff. If you’ve got a production rack where downtime is expensive and you don’t want to play the “will it link or will it hunt for optics firmware/compatibility quirks” game, paying for the right branded cable can be reasonable.

That said, I wouldn’t buy this purely because it’s Dell or because it says “InfiniBand/fibre”. You should only purchase it if you’ve confirmed the interface type on both ends (and that you truly need this exact cable assembly, not standard fibre jumpers or different QSFP28 interconnects). In many datacentre setups, third-party or non‑Dell equivalents can work just as well for the right length/connector style, so if you’re flexible and have spares/verification time, you might get better value elsewhere. If you tell me what equipment it’s going between (switch/NIC models) and whether it’s IB FDR/EDR/HDR, I can be more definitive on whether this price is fair.
