DELL 470-AAVJ InfiniBand/fibre optic cable 3.048 m SFP+ Black

Product Overview

AI-generated summary

Honestly, I’d only buy this kind of Dell-branded SFP+ cable if you already know your environment specifically needs it. The biggest practical issue with these “cable-only” optics is compatibility: you’re tying yourself to a particular port type, partner optics/cabling rules, and vendor expectations. In real server-room life, that can mean more time confirming supported links than actually deploying. If you’re wiring up InfiniBand or a fibre-backed fabric where link requirements are strict, that specificity can be worth it.

At £54.64 ex-VAT for a 3m run, it’s not a bargain price, but it’s also not outrageous if you’re avoiding troubleshooting downtime or re-purchasing the wrong thing. This is a “buy for certainty” item: good for standardised deployments where you’re matching what’s already in the racks. I wouldn’t bother if you’re in a mixed-vendor setup or you’re still working out whether copper/different optics would work—then you’ll likely lose the savings to returns and verification. If you tell me what switch/HCA model it’s going into, I can give you a clearer “yes, buy” versus “no, waste of time” take.
