Product Overview

AI-generated summary

At ~£449 ex-VAT, this Cisco-branded 1GbE SFP (single‑mode LC, long-haul LX/LH class, 10km range) is the kind of module that makes sense only when you actually *need* the optics for distance and you want Cisco-friendly compatibility with specific Cisco gear. If you’re extending fibre links between core/distribution switches or to an uplink rack over a proper single‑mode run, it can be a very safe “works first time” choice—especially in environments like 38XX/39XX/Catalyst 29XX/3650/ME 3600/ESS9300 where you don’t want the usual firmware/DOM/compatibility headaches.

That said, I’d push back if you don’t strictly need long‑reach single‑mode. For short runs (or if you’re just topping up spare ports), the price is hard to justify versus cheaper SFP equivalents from reputable third parties—assuming your network tolerates them. Also, “Cisco for Cisco” is great… until you end up paying Cisco tax every time you expand. So: buy this if you’re standardising on Cisco optics for long‑reach single‑mode and you want maximum interoperability. Don’t buy it if your link distance doesn’t require it, or if you’re trying to keep module spend under control on a bigger project.
