AI-generated summary
If you’re buying a 1m Dell QSFP+ InfiniBand/fibre optic cable, this is the kind of “small part that stops big problems” purchase. For short runs—like inter-rack connections or top-of-rack to nearby switch gear—1m is exactly the right length, and using a branded optic/cable is often about reducing headaches during commissioning and fault-finding. At £106.10 ex-VAT, it’s not cheap, but it’s not wildly overpriced either for something that’s meant to behave reliably in tightly managed enterprise networking.
That said, I’d only buy this if you’re 100% sure it’s the correct cable type for your QSFP+ ports and your InfiniBand/fibre setup (and that your environment actually expects this specific Dell-qualified cable). If you’re just trying to “get a link up” on a mixed or generic network, spend time validating compatibility first—because the cost of one wrong cable and the time lost can erase any savings. If you have multiple short links, consider budgeting for spares too; these are the cables you’ll be grateful you didn’t wait to order when something fails.
**Who should buy:** IT teams/resellers supporting Dell QSFP+ InfiniBand/fibre deployments with short internal cabling runs where compatibility and troubleshooting simplicity matter. **Who shouldn’t:** anyone without confirmed port/cable compatibility, or anyone needing longer distances where you’ll be paying for the wrong length.
