Lenovo 3m LC-LC OM3 InfiniBand/fibre optic cable 118.1" (3 m)

Product Overview

AI-generated summary

At £120 ex-VAT for a 3m OM3 LC-to-LC InfiniBand/fibre cable, this is one of those “you’ll only care about the part number” purchases. If you’ve already standardised on Lenovo’s cabling ecosystem (or you’re trying to match an existing InfiniBand build) it’s sensible: proper length, correct connectors, and you avoid the usual faff of compatibility questions and return cycles. For a small rack, lab, or a tightly laid-out datacentre row where 3m is exactly what you measured, it’s good value compared to experimenting with generic leads and ending up troubleshooting signal issues that aren’t worth your time.

That said, I wouldn’t buy this if you’re building new cabling from scratch and you don’t have a reason to stick with Lenovo-branded parts. Fibre is fibre—what matters is correct multimode type and connector format for your link—so you can often find equivalent non-branded or OEM alternatives cheaper. Also, 3m can be a trap: if there’s any chance you’ll need routing flexibility, you may be better buying a slightly longer option once, rather than ending up with extra spares or rework. Buy it if you’re replacing/standardising an existing Lenovo setup; skip it if you’re shopping purely on price and flexibility.
