Lenovo 4XC1R00857 network card Internal Fiber 10000 Mbit/s

Product Overview

AI-generated summary

For £293.82 ex‑VAT, a Lenovo internal fibre NIC that’s “10000 Mbit/s” is a fairly expensive way to solve a very specific problem. In real-world terms, fibre 10GbE is brilliant when you’re moving lots of data between servers, storage, or a small rack setup and you want stability over distance and less noise than copper. If you already have compatible 10Gb fibre switches/transceivers and a clean optical path, this kind of adapter can be a straightforward upgrade: good build quality, enterprise-brand reliability, and easy integration in typical Lenovo server environments.

That said, I wouldn’t buy it just because “10Gb is faster.” The hidden costs are compatibility and optics: you need the right transceivers/cabling and you need it to match your server’s slot and platform support—Lenovo parts are usually fine, but you still want to confirm it’s supported in your exact model and that the switch side will negotiate the way you expect. If you’re a normal SMB with modest throughput needs or you’re mostly streaming to a single NAS, that spend is hard to justify versus a cheaper copper option or even postponing the upgrade. This is best for IT teams doing proper 10Gb fibre networking, not for quick lab boosts or one-off file sharing.
