Adaptateur Ethernet D-Link DUB-E250 USB-C vers 2.5G

The D-Link DUB-E250 USB-C to 2.5G Ethernet adapter upgrades laptops and desktops with a USB Type-C port to multi-gigabit wired connectivity. Compact and USB-powered, it delivers up to 2500 Mbit/s in a white, pocketable design and is compatible with existing Fast Ethernet and Gigabit networks.

Advantages

The adapter provides 2.5 Gbps Ethernet speeds over a single USB-C connection, more than twice the throughput of standard Gigabit Ethernet. It includes a preloaded driver for instant plug-and-play installation, a compact portable form factor, and dynamic power management that reduces power draw when traffic is light, idle, or the cable is unplugged.

Suitable for

• Ultra-thin laptops and notebooks with USB-C / Thunderbolt 3 ports and no built-in Ethernet
• Desktops needing a quick multi-gigabit upgrade without opening the case
• Transferring large files, backups to NAS or servers, and other network-intensive tasks
