For £15.46 ex-VAT, this TP-Link Omada RJ45 SFP module is a cheap and cheerful way to get copper gigabit connectivity where your switch has an SFP slot but you don’t want to change hardware. If you’ve got patching or a deployment plan that hinges on “one switch, mixed media,” it’s genuinely handy: you can drop this in and run up to ~100m on decent Cat5e+ without fuss. The “plug and play” angle matters in the real world—less faffing, fewer compatibility headaches during rollout.
That said, I wouldn’t buy these for every situation. If you just need basic copper ports, a native RJ45 switch port is usually cleaner (and often less trouble over time with optics-management quirks or edge-case compatibility). Also, you’re paying for flexibility—so if you’re only ever going to use fixed RJ45 connections, you might get better long-term value by choosing hardware that already matches your cabling plan. Who it suits best: Omada users with SFP-capable switches who need extra copper runs on a budget, especially for access/edge links around a site. If you’re planning something more complex (lots of different transceiver types, mixed vendors, or long lifecycle support), I’d sanity-check the exact switch model’s transceiver compatibility first.
