Product Overview

AI-generated summary

At £14.38 ex-VAT this is the kind of “it’ll probably work” optics you buy when you’re topping up a budget spares kit or doing a straightforward lab/office run and you don’t want to pay enterprise tax. It’s a single-mode SFP+ with LR-class reach, so it makes sense for short-to-medium distances over fibre where you need 10GbE and LC connectors. The real question isn’t the headline compatibility—it’s whether your specific switch/network gear accepts StarTech-branded optics cleanly and whether it supports the optical module type your setup expects.

I’d buy this if you’re confident your switches support third-party SFP+ modules (and ideally you’ve used StarTech before), and you want good value for a non-mission-critical link, like extra rack interconnects or a spare you can swap quickly. I’d hesitate if you’re running something critical where an optics quirk would be painful: some manufacturers are picky, and if DDM/operational thresholds don’t line up, you can end up with annoying warnings or reduced reliability. If you tell me the exact switch model (and whether it’s an SFP+ port or an SFP+ transceiver cage), I can give a more confident “yes, buy” versus “test first.”
