Product Overview

AI-generated summary

For £85 ex-VAT, this AddOn SFP+ (10GBase-LR, 1310 nm) looks like a sensible “keep the network running” purchase—especially if you’re trying to replace a failed module without paying OEM pricing. LR optics are typically the right call for longer runs over single‑mode fibre, and in day-to-day use they’re pretty boring in the best way: if your switch and optics are happy, you just plug it in and move on. The real value here is cost vs. downtime: if you’re stocking spares or you manage a lot of 10G links, cheap-but-compatible optics can save serious money.

That said, I’d only buy it if you’ve confirmed compatibility with the exact platforms you listed (and ideally you’ve seen them work in your specific environment). With third-party optics, the usual risks are vendor compatibility/DOM quirks, finicky behaviour during link negotiation, or surprises when you firmware/patch the switch later. If this is mission-critical production where “no faff” matters more than price, OEM modules are the safer route. If you’re comfortable testing in a non-critical window (or you already trust this brand in your gear), then this is a good budget option. For most buyers, I’d describe it as: great for spares, not something I’d choose for your single highest-availability link without verification.
