DELL 2X15K network transceiver module Fiber optic 100000 Mbit/s QSFP28 850 nm

Product Overview

AI-generated summary

At £860.21 ex-VAT for a Dell-branded QSFP28 850 nm module, this is one of those “it’s fine, but only if you’re in the right environment” purchases. You’re paying a premium for a known Dell part, and in practice these modules make most sense when you need guaranteed compatibility with specific Dell switch platforms and your links are short-range multimode (typical in data centres). If you’re swapping like-for-like in a supported Dell stack, the operational headache drops massively—less time troubleshooting optics, less chance of flakey link training, and fewer “it should work” moments.

I wouldn’t buy this for anything loosely related to your current network or if you’re planning longer distances: 850 nm multimode optics can be very cost-effective within the right cabling footprint, but they won’t magically replace an optics choice tuned for longer reach or single-mode requirements. Also, £860 isn’t the cheapest route—if you’re just topping up ports and you’ve validated your vendor/part compatibility, you might get better value with alternatives that your switch reliably supports. Bottom line: buy it if you’re doing supported Dell QSFP28 multimode installs and want low-risk replacement; think twice if you’re uncertain about optics type, fibre type, or expected reach, or if you’re price-sensitive and can source compatible non-premium options.
