AI-generated summary

For £18.85 ex-VAT, this is the sort of “keep the network patched and moving” SFP+ that makes sense when you just need a known-good 10GBASE-LRM link over multimode at short-to-moderate reach. StarTech’s Cisco-compatible optics are usually a decent value for routine spares—especially if you’re managing a mixed Cisco estate and don’t want to pay big-brand pricing for every replacement. The fact it’s marketed for platforms like Firepower/ASR/Catalyst tells me it’s aimed at people who need straightforward drop-in swaps rather than messing around with workarounds.

That said, I’d only buy this if your environment matches what LRM is actually good at: multimode fibre and the distances you’re trying to cover. If you’re anywhere near the edge of compatibility on a particular switch port or fibre patching scenario, cheaper optics can be the first thing that causes flaky link behaviour—so sanity-check your existing module in that same port first, or confirm your switch supports the exact optical type you’re intending to run. If you need maximum “it always just works” and long-term support, OEM optics still win on peace of mind, but for cost-conscious resellers and everyday spares, this is a strong buy for the right use case.
