Product Overview

AI-generated summary

At £39.92 ex-VAT, this looks like a solid “keep the network running” SFP+ add-on if you’re dealing with short-to-medium reach multimode fibre. The key bit is that it’s an LRM (long reach multimode) transceiver for 10GbE, so it’s typically the right choice when you can’t justify swapping fibre runs or moving up to single-mode. For UK office/warehouse networks, server uplinks, and patch-panel work where distances are around the ~200m ballpark, this kind of module is usually good value—especially if you’ve got a Juniper-compatible platform and just need spares/renewals without paying premium OEM pricing.

That said, I wouldn’t buy this blindly if you’re trying to “make it work” across unknown fibre quality. SFP+ optics can be very sensitive to the actual fibre grade, cleanliness, and connector condition; cheap multimode links are fine until they aren’t. Also, because this is an aftermarket-compatible module, your real risk isn’t the module itself—it’s whether your exact switch model/firmware is happy with it and what the optics diagnostics show. If you have a validated compatible list (or you can test on a spare port first), then it’s a sensible purchase. If you’re building something critical with no room for retries, I’d lean toward OEM or at least a reseller that provides compatibility confirmation.
