DELL 470-ABPW InfiniBand/fibre optic cable 0.5 m QSFP28 Black

Product Overview

AI-generated summary

Honestly, this is the kind of cable you buy because you *have to*, not because it’s a bargain. A 0.5m Dell QSFP28-style fibre lead at £164.53 ex-VAT isn’t “cheap cabling” — it’s priced like a guaranteed compatibility part. If you’ve got an InfiniBand or fibre switch/transceiver setup from Dell and you’re trying to avoid weird link drops, negotiation issues, or support headaches, using Dell-branded optics/cabling can be worth it, especially in a production environment where downtime is expensive.

Who should buy: data centres, HPC clusters, and managed networks where the ports and optics are already Dell/compatible and your run is genuinely short (0.5m). If you’re connecting like-for-like in a rack and you just need something that works first time, this is sensible. Who shouldn’t: if you’re just “trying to get fibre working” for a lab or low-criticality environment, it causes you to pay premium prices for a cable you could often source cheaper (as long as the end devices support it and your vendor compatibility is clear). Also, double-check that you truly need this connector/form-factor for QSFP28 on both ends — buying the wrong fibre cable length/type will cost you twice.
