DIGITUS DN-3026 — USB 3.0 Gigabit SFP Network Adapter
Gigabit fibre1× SFPUSB-A 3.0Realtek RTL8153
The DIGITUS DN-3026 is an USB 3.0 to Gigabit SFP fibre network adapter that adds a wired Gigabit Ethernet port to a laptop, desktop PC, tablet or thin client through its USB-A port. Instead of an RJ45 socket it has an SFP slot, so a laptop or PC can connect straight to a fibre network with a Gigabit SFP module. It is built on the Realtek RTL8153 controller and connects at 1000 Mbps (1000BASE-SX/LX via SFP). It draws its power from the USB port, so there is no separate power supply to carry. A cable connection is the dependable answer when Wi-Fi is weak, crowded or not allowed, when a slim laptop has no network socket, or when backups, large downloads and video calls need a steady, low-latency link.
Compatibility — check before buying:
Check the port: the adapter has a USB-A plug; on a laptop that only has USB-C ports, choose a USB-C model instead. It links at up to 1 Gbps with any standard switch or router port, and Cat5e cable or better is enough. No SFP module included and Gigabit only: use a 1000BASE-SX or LX SFP module; SFP+ 10G modules will not work. DIGITUS now lists DN-3026-1 as the current SFP adapter. Operating systems listed by DIGITUS: Windows, macOS, Chrome OS. Not sure it suits your laptop, dock or switch? Tell us the model and we check it.

Frequently Asked Questions
Do I need to install a driver?
Supported systems listed by DIGITUS: Windows, macOS, Chrome OS. Where the system does not load a driver on its own, install the driver from the DIGITUS support page for this model.
Is it faster than Wi-Fi?
A wired Gigabit link gives up to 1 Gbps with steadier latency than most Wi-Fi connections — that is what video calls, remote desktop and large transfers benefit from. Your internet speed still depends on your connection.
Will it work on a USB-C-only laptop?
Not directly — it has a USB-A plug. For USB-C laptops choose a USB-C version of this adapter.
Is an SFP module included?
No. Add a 1000BASE-SX (multimode) or LX (singlemode) SFP module that matches your fibre and switch.
