Product Overview

AI-generated summary

At £415 ex-VAT, this is one of those “works great, costs a lot” Cisco SFP+ optics. For the right setup, you’ll be glad you paid it: Cisco is usually picky with transceivers, and using the intended modules for those platforms tends to mean fewer compatibility headaches and a cleaner operational life than hunting for cheaper third-party optics that may or may not behave exactly the same. The 300 m/850 nm multimode fit is also the kind of distance that maps neatly to typical data-centre patching, so it’s a sensible choice when you know your fibre type and run length are in-range.

Who should buy it: teams running the listed Cisco switches (Catalyst ESS9300, Nexus 5010, and those specific switch modules) who want predictable performance, standard behaviour, and minimal hassle during install and maintenance. Who should think twice: if you’re trying to stretch budget, have lots of spare ports, or your environment can tolerate non-Cisco optics, you’ll often find cheaper options—but you need to validate compatibility carefully first (otherwise “saving money” turns into chasing optics errors, flaps, and support tickets). If you only need a one-off and downtime/compatibility risk matters, this is a fair “pay to avoid pain” purchase. If you’re buying at scale, I’d pressure-test pricing versus verified alternatives before committing.
