Product Overview

AI-generated summary

At ~£23 ex‑VAT, this is the kind of “get the link back up” SFP you buy when you already know you’ve got compatible multmode fibre optics and you just want reliability without paying OEM tax. StarTech calling it “Palo Alto Networks SX compatible” is the key detail here: if your Palo Alto switch/SFP cages are expecting 850nm SX optics on multimode with LC connectors, this should slot in cleanly and do the job. The inclusion of DDM is a nice practical touch too—on real networks it helps you catch issues early (power/temperature drift) instead of guessing when links start flapping.

I’d recommend it for small-to-mid UK deployments, MSPs, or anyone maintaining network gear where downtime is expensive and the optics are predictable. If you don’t already have multimode fibre built for SX, though, don’t bother—this isn’t a “universal SFP” substitute, and trying to use it on the wrong fibre type or with the wrong optics expectation will waste time fast. Also double-check you’re buying the correct SFP form factor for the exact Palo Alto model you’re plugging it into; compatibility labels can be helpful, but they’re not a substitute for verifying the vendor’s supported optics list.
