Lenovo 49Y7884 network transceiver module 40000 Mbit/s SFP+

Product Overview

AI-generated summary

If you’re seeing the Lenovo-branded 49Y7884 for £1,519.58 ex-VAT, you should be confident you *actually* need a module of this type and that it’s going to work first-time in your exact switch/NIC environment. In real UK data rooms, the biggest “gotchas” with transceivers aren’t performance on paper—they’re compatibility, transceiver authentication, and supportability. With OEM optics like this, you typically get fewer surprises than with no-name compatibles, but you’re also paying for that peace of mind. If you’re running Lenovo kit (and ideally in a Lenovo ecosystem), it can be a sensible replacement so you don’t end up troubleshooting link training and vendor quirks at 2am.

Who should buy: teams maintaining existing Lenovo networking gear and replacing a failed SFP+ with minimal downtime, where support contracts and “known-good” compatibility matter more than saving a bit of money. Who should *think twice*: buyers who don’t have a clear need for this exact module class, or who are likely to shop around for cheaper third-party optics—because the savings can disappear fast if you hit compatibility issues or end up with limited warranty/diagnostics. For £1,519.58, I’d only proceed if you can verify the exact part match for your switch model and current optics configuration; otherwise, there are usually better-value ways to source optics for the same ports.
