Lenovo 7Z57A03548 InfiniBand/fibre optic cable 10 m QSFP28 Blue

Product Overview

AI-generated summary

If you’re paying £1,288 ex-VAT for a 10m Lenovo InfiniBand/fibre optic cable, you’d better have a very specific use case. This is the sort of link you buy when you’re building or extending a managed InfiniBand fabric (or matching a vendor-specific setup) and you need something that will “just work” with minimal faff—especially where optics, lane mapping, and transceiver compatibility have historically been pain points. For data centres and serious HPC/SAN-style environments, the cost can be justified because downtime and troubleshooting hours dwarf the cable spend.

That said, I wouldn’t buy this casually or for generic networking. If you simply need fibre for standard switches/racks and your gear isn’t InfiniBand/QSFP28 in a way that expects this cable format, you’ll almost certainly be overpaying. Also, 10m isn’t “universal”—if your routing is even slightly uncertain, it’s worth double-checking path length and slack requirements rather than assuming you can “make it fit”. In short: buy it only if you’re extending an InfiniBand QSFP28 environment where Lenovo parts reduce compatibility risk. If not, there are usually better-value, correctly-rated alternatives.
