StarTech.com Dell EMC SFP-1G-BX80-D Compatible SFP Module - 1000BASE-BX-D - 1 GbE Gigabit Ethernet BiDi Fiber (SMF)

Product Overview

AI-generated summary

At £16 ex-VAT, this is the kind of “just works” SFP that makes sense for businesses that need spares or replacements for existing fibre runs without paying Dell EMC’s branded tax. It’s bi-directional, so it’s aimed at the common BX use case where you’ve got a single fibre pair arrangement behaving like two directions on one fibre path. If you already have a compatible switch/transceiver setup in place and you’ve confirmed you’re using SMF with the right wavelength pairing, this is a cost-effective way to keep links up when something goes wrong.

That said, I wouldn’t buy this blindly for a new design. SFP compatibility can be picky: some switch models are more tolerant of third-party optics than others, and with SFPs the “wrong” optics can lead to marginal link stability or no link at all. Also, check that your existing fibre side matches the expectations (bi-di + SMF + the relevant transceiver type for your link partner). If you’re doing quick maintenance, holding a spare, or you’ve already got the exact same module working in your environment, it’s great value. If you’re building or troubleshooting a live network and can’t verify compatibility first, I’d spend a little more time confirming support before you click buy.
