Product Overview

AI-generated summary

At ~£23 ex-VAT, this StarTech/Arista-compatible 1GBASE-LX SFP is exactly the kind of low-cost “get it working” option that makes sense in a lot of UK offices. If you need a straightforward single‑mode link over up to around 10km using LC fibre, it’s a sensible buy—especially for spare/repair stock where you want predictable behaviour rather than gambling on the cheapest compatibles. The DDM support (so you can see link/laser info in the switch) is the difference between “it’s plugged in” and “we can actually monitor and troubleshoot it.”

Who should buy it: MSPs, resellers, and IT teams maintaining site-to-site or long run fibre where you’re using Arista gear that expects this type of module. It’s also good for budget-conscious upgrades where you don’t need anything beyond 1GbE LX. Who should think twice: if this is for mission-critical, heavily monitored backbones where you want the absolute lowest risk from a brand-new module line, you may prefer OEM optics—or at least buy in bulk and test in your specific switch model first. Also, double-check you’re in single‑mode (SMF) fibre and the far end is matched correctly; SFPs won’t rescue bad fibre assumptions.
